The mill (American English) or mil (Commonwealth English, except Canada) is a unit of currency, used in several countries as one-thousandth of the base unit. It is symbolized as ₥ (U+20A5 ₥ MILL SIGN).[a]
In the United States, it is a notional unit equivalent to a thousandth of a United States dollar (a hundredth of a dime or a tenth of a cent). In the United Kingdom, it was proposed during the decades of discussion on decimalisation as a 1⁄1000 division of the pound sterling. While this system was never adopted in the United Kingdom, the currencies of some British or formerly British territories did adopt it, such as the Palestine pound and the Maltese lira.
The term comes from the Latin "millesimum", meaning "thousandth part".[1]
Usage
[edit]United States
[edit]
In the United States, the term was first used by the Continental Congress in 1786, being described as the "lowest money of account, of which 1000 shall be equal to the federal dollar".[2]
The Coinage Act of 1792 describes milles and other subdivisions of the dollar:
That the money of account of the United States shall be expressed in dollars or units, dismes or tenths, cents or hundredths, and milles or thousandths, a disme being the tenth part of a dollar, a cent the hundredth part of a dollar, a mille the thousandth part of a dollar, and that all accounts in the public offices and all proceedings in the courts of the United States shall be kept and had in conformity to this regulation.[3]
The US Mint in Philadelphia made half cents worth 5 mills each from 1793 to 1857.
Tokens in this denomination were issued by some states and local governments (and by some private interests) for such uses as payment of sales tax.[4] These were of inexpensive materials such as tin, aluminium, plastic or paper. Rising inflation depreciated the value of these tokens in relation to the value of their constituent materials; this depreciation led to their eventual abandonment. Virtually none were made after the 1960s.
Today, most Americans would refer to fractions of a cent rather than mills, a term that is widely unknown. For example, a gasoline price of $3.019 per gallon, if pronounced in full, would be "three dollars [and] one and nine-tenths cents" or "three <point> zero-one-nine dollars". Discount coupons, such as those for grocery items, usually include in their fine print a statement such as "Cash value less than 1⁄10 of 1 cent". There are also common occurrences of "half-cent" discounts on goods bought in quantity. However, the term "mill" is still used when discussing billing in the electric power industry as shorthand for the lengthier "1⁄1000 of a dollar per kilowatt hour". The term is also commonly used when discussing stock prices, the issuance of the founder's stock of a company, and cigarette taxes.
Property tax
[edit]Property taxes are also expressed in terms of mills per dollar assessed (a mill levy, known more widely in the US as a "mill rate"). For instance, with a millage rate of 2.8₥, a house with an assessment of $100,000 would be taxed (2.8 × 100,000) = 280,000₥, or $280.00. The term is often spelled "mil" when used in this context.[5]
With respect to property taxes, a "mil" is also slang for one million units of currency, especially as a rate expressed per mille "‰", as one million units of currency per milliard on the long scale of numeration, that is, 1,000,000 per 1,000,000,000 currency units of assessed valuation on all private property throughout the "mill yard" or property tax levy district.
Finance
[edit]The term mill is often used in finance, particularly in conjunction with equity market microstructure.[6] For example, a broker that charges 5 mils per share is taking in $5 every 1000 shares traded. [dubious – discuss][7] Additionally, in finance the term is sometimes spelled "mil".[8] Cf. basis point.
Some exchanges allow prices to be accounted in ten-thousandths of a dollar ($29.4125 = 29,412.5₥ for example). This last digit is sometimes called a "decimill" or "deci-mill", but no exchange officially recognizes the term.
Fiction
[edit]Mark Twain introduced a fictional elaboration of the mill in his 1889 novel A Connecticut Yankee in King Arthur's Court. When Hank Morgan, the American time traveler, introduces decimal currency to Arthurian Britain, he has it denominated in cents, mills, and "milrays", or tenths of a mill (the name perhaps suggested by "myriad", meaning ten thousand or by the Portuguese and Brazilian milreis).
Canada
[edit]This section may incorporate text from a large language model. (September 2025) |
In Canada, the mill rate system is fundamental for calculating property taxes at the municipal level, reflecting the amount of tax per $1,000 of assessed property value. Municipalities determine annual mill rates based on budget needs for public services like education, infrastructure, healthcare, and law enforcement.
This calculation helps standardize property taxes while allowing flexibility to address specific financial needs in each locality. Mill rates are subject to adjustment annually or periodically, depending on factors like government spending requirements, economic conditions, and shifts in property valuations, providing a fair and balanced approach to local tax funding.
For example, if a property is valued at $100,000 and the mill rate is set at 50, the tax due would be calculated as: 100,000 × (50 / 1000) = 5,000. This straightforward calculation offers transparency for taxpayers and aids municipalities in consistent revenue collection.[9]
United Kingdom
[edit]Proposed on several occasions as a means of decimalising sterling under the "pound and mil" system suggested in 1855 by Sir William Brown MP,[10] the mil was occasionally used in accounting.
The 1862 report from the Select committee on Weights and Measures[11] noted that the Equitable Insurance Company had been keeping accounts in mils (rather than in shillings and pence) for such purposes for over 100 years. Such a unit of a thousandth of a pound would have also been similar in value to the smallest coin in circulation, the farthing (worth 1⁄960 of a pound).
By the time British currency was decimalised in 1971, the farthing had been demonetised eleven years prior, in part due to having its value eroded by inflation; thus, the mil was no longer necessary.
Malta
[edit]The Maltese lira was decimalised in 1972 on the "pound and mil" system. The coinage included denominations of 2 mils, 3 mils, and 5 mils from 1972 to 1994, with 10 mils being equal to one cent. While prices could still be marked using mils until 2008, when the country switched to the euro, in practice these were rounded off for accounting purposes.
Mandatory Palestine, Israel, Jordan
[edit]
The Palestine pound, used as the currency of the British Mandate for Palestine from 1927 to 1948, was divided into 1,000 mils. Its successor currencies, the Israeli lira and the Jordanian dinar retained the 1⁄1000 division, respectively named the pruta and fils. The Israeli pruta lasted until 1960, and the Jordanian fils until 1992, and in Supermarket prices and taxi meters well into the 21st century.
Hong Kong
[edit]Between 1863 and 1866 the one mil coin was the lowest denomination issued by the British government in Hong Kong; it was eliminated due to its unpopularity.[12]
Cyprus
[edit]The Cypriot pound was decimalised using the "pound and mil" system in 1955 and lasting until 1983. However, coins smaller than 5 mils ceased being used in the mid 1960s. When switched to cents in 1983, a ½-cent coin was struck that was abolished a few years later.

Mill (currency)
View on GrokipediaDefinition and Etymology
Definition
A mill (sometimes spelled mil) is a unit of currency equal to one-thousandth (1/1000) of a base currency unit, such as the dollar or pound.[7] In legal terms within the United States, it is explicitly defined as a thousandth of a dollar.[1] The mill is symbolized by ₥, a character designated in Unicode as U+20A5 (mill sign),[8] historically associated with representing one-tenth of a cent in American usage. In decimal currency systems where the base unit divides into 100 subunits (like cents), one mill equates to 0.1 cent, providing finer granularity than the cent for monetary expressions.[7] In contemporary practice, the mill functions primarily as a notional or accounting unit rather than a physical denomination, enabling precise calculations in areas such as taxation and billing without requiring actual coinage.[3] This abstract role underscores its utility in financial systems where sub-cent accuracy is needed, though it rarely circulates in tangible form today.Etymology
The term "mill" in the context of currency derives from the Latin word millesimum, meaning "thousandth," which directly reflects its role as a unit representing one-thousandth of a base currency.[9] This etymological root emphasizes the numerical precision of fractional accounting, tracing back to classical Latin usage for denoting small divisions.[3] The first recorded English usage of "mill" as a currency unit appeared in 1786, introduced by the Continental Congress as a notional subdivision of the dollar, influenced by the need for finer monetary granularity in early American accounting.[9] This adoption drew from broader traditions of using thousandth-based fractions in financial records, though the specific term entered common parlance in the late 18th century.[10] Variants of the term include "mil," prevalent in English-speaking regions for the same thousandth unit, derived from Latin mille ("thousand").[11] In Arabic-influenced areas of North Africa, such as Tunisia and Libya, the equivalent is "millieme," borrowed from French millième ("thousandth"), which itself stems from the Latin millesimum.[12] Notably, this currency-related "mill" has no linguistic connection to the English word for a grain-grinding apparatus, which originates from a separate Latin root, molina.[10]History
Early Adoption in the United States
The Continental Congress proposed the mill as part of efforts to standardize the post-Revolutionary War currency system, adopting a decimal-based structure to replace the varied colonial monies. On August 8, 1786, Congress resolved to establish the mill as the lowest unit of account, defined as one-thousandth (1/1000) of the dollar, with the system proceeding in a decimal ratio to enable precise divisions: 1 dollar = 10 dimes = 100 cents = 1,000 mills.[13] This framework aimed to simplify accounting and trade by aligning with natural decimal progressions, facilitating small-scale transactions in an economy transitioning from British pounds, shillings, and pence.[13] The mill received formal legislative definition in the Coinage Act of 1792, which established the United States Mint and codified the mill explicitly as one-thousandth of a dollar within the decimal currency system.[14] The act authorized the production of copper coins, including the half cent valued at one-two-hundredth of a dollar, equivalent to 5 mills, to support everyday commerce and accurate bookkeeping without the need for fractional silver pieces.[14] Half-cent coins, struck from pure copper, were first minted in 1793 at the Philadelphia Mint and continued production intermittently through 1857, serving as the physical embodiment of the mill's utility in minor exchanges.[15] By the mid-19th century, the half cent's intrinsic value had diminished relative to rising copper costs and economic changes, leading to its discontinuation as a circulating coin under the Coinage Act of 1857.[16] No smaller denominations were minted thereafter, as the coin's negligible purchasing power rendered it impractical for production.[16] However, the mill persisted as a notional unit in the U.S. monetary framework, retaining its role in decimal accounting and financial calculations despite the absence of physical representation.[14]Spread to Other Regions
The concept of the mill as a subunit of currency, originally established in the United States through the Coinage Act of 1792, began influencing British colonial monetary systems in the 19th century as part of broader discussions on decimalization.[17] In 1855, a British parliamentary committee on decimal coinage proposed adopting the mil for copper denominations to facilitate a decimal-based system, drawing on American precedents to simplify subdivisions of the pound.[18] This influence spread through the British Empire, notably to Hong Kong, where the first mil coins were issued in 1863 under Queen Victoria as bronze pieces valued at one-thousandth of the Hong Kong dollar, marking an early adaptation of decimal subunits in colonial coinage.[19] Similarly, in Mandatory Palestine, the Palestine pound was introduced in 1927 by the British Mandate authorities, explicitly divided into 1,000 mils to align with sterling's value while incorporating decimal divisions for administrative efficiency.[20][21] Under British mandates in the Mediterranean and Middle East, the mill was integrated into local currencies, often building on Ottoman-era systems but adapting them to decimal frameworks. In Cyprus, a British colony from 1878, the pound was decimalized in 1955 and subdivided into 1,000 mils, replacing the earlier non-decimal system of piastres and shillings. This persisted until a 1983 reform shifted the subdivision to 100 cents.[22] In Egypt, under significant British influence from the late 19th century, the Egyptian pound—pegged to sterling—was divided into 100 piastres and further into 1,000 milliemes (mils) starting in 1916, reflecting colonial standardization of small-value transactions.[23] Malta, another British territory with Ottoman historical ties, incorporated the mil into its decimalized lira in 1972, where 1 cent equaled 10 mils until the mils were discontinued and removed from circulation in 1994; the currency transitioned to the euro in 2008.[24] These adaptations highlighted the mill's utility in regions transitioning from non-decimal Ottoman paras and piastres to imperial-aligned systems. Post-colonial legacies of the mill endured particularly in tax administration across former British territories, where it persisted as a "mill rate" for property taxation despite broader currency decimalizations or adoptions of new units like the euro. In Canada, inherited from British colonial practices, municipalities continue to use mill rates—tax per thousand dollars of assessed property value—for local levies, as documented in provincial assessment guides and historical revenue statistics.[25][26] This retention in fiscal systems, even as circulating currencies evolved, underscores the mill's enduring administrative role in ex-colonial contexts from North America to the Mediterranean.[27]Usage by Country
United States
In the United States, the mill persists as a unit in various non-physical applications, particularly in taxation, finance, and billing, where it facilitates precise calculations for fractional cent amounts. Property taxes are commonly assessed using the millage rate, which represents the tax levied per $1,000 of assessed property value.[28] The tax is calculated with the formula: For example, a millage rate of 2.8 mills applied to a property assessed at $100,000 results in an annual tax of $280.[29][30] This system, set by local governments including counties, municipalities, and school districts, allows for granular funding of public services without relying on physical currency.[28] In financial markets, the mill—equivalent to one-thousandth of a dollar or 0.1 cent—appears in stock trading commissions and exchange fees. Brokers and exchanges historically charged rates like 5 mils per share, amounting to $0.005 per share traded.[31] Regulatory caps, such as the Securities and Exchange Commission's limit of 30 mils per share for access fees on protected quotations priced at $1 or more, continue to reference mills to control trading costs.[32] Utility billing also employs mills, especially for electricity rates expressed per kilowatt-hour. For instance, some federal power marketing administrations set base energy charges at 12.35 mills per kilowatt-hour, with adjustments for factors like power purchase costs.[33] This usage enables accurate pricing of wholesale and retail energy without rounding to full cents.[34] The mill features in American literature as a symbol of modern economic systems, notably in Mark Twain's 1889 novel A Connecticut Yankee in King Arthur's Court, where the time-displaced protagonist Hank Morgan reforms medieval England's economy by introducing a decimal-based currency including dollars, cents, and mills to promote efficiency and fairness.[35] Unofficial mill tokens, produced by states and private entities, circulated until the 1960s to collect sales taxes on purchases under one cent, such as a 2-mill token for fractions of a penny.[36][4] These were never federally recognized as coins, following the Coinage Act of 1857, which discontinued U.S. half-cent pieces (worth 5 mills) and smaller denominations to streamline circulation.[15]Canada
In Canada, the mill is employed exclusively as a unit in property tax calculations, specifically through mill rates set by municipalities since the late 19th century. This practice originated with the establishment of municipal taxation systems in provinces like Ontario and spread nationwide, with mill rates standardized as the tax levied per $1,000 of a property's assessed value. For instance, a mill rate of 50 applied to a property assessed at $100,000 results in an annual tax of $5,000, determined by the formula: tax = (assessed value × mill rate) / 1,000.[37][38] Municipal governments administer these mill rates to fund essential local services, including infrastructure maintenance, public safety, and contributions to education, without any issuance of physical mill-denominated currency. Property taxes collected via mill rates form a primary revenue source for Canadian municipalities, varying by province but uniformly calculated to ensure equitable distribution based on assessed values determined by provincial assessment authorities. Unlike circulating currency, the mill remains an abstract fiscal tool confined to taxation, with no documented applications in broader financial systems or cultural contexts. As an example, in Toronto, the 2023 residential mill rate for the municipal portion was approximately 5.06 mills, part of a total effective rate of 6.66 mills when including education and other levies, and these rates are adjusted annually by city council to align with budgetary needs.[39][40] This system reflects a consistent provincial framework, as seen in historical data from Ontario where mill rates exceeded 40 mills in the mid-20th century for urban properties.[41]United Kingdom
In the mid-19th century, the United Kingdom considered the mill as a potential subunit of the pound sterling during debates on currency decimalization to simplify accounting and commercial calculations. A Select Committee of the House of Commons appointed in 1853 examined various schemes and recommended a "pound-mils" system, subdividing the sovereign into 1,000 mils, with proposed coins including 1, 2, 5, 10, 25, 50, and 100 mil denominations to replace or adjust existing copper and silver pieces.[18] This approach drew inspiration from the decimal structure of the U.S. dollar established in 1786, aiming for alignment with international trade practices while retaining the pound as the primary unit.[17] The proposal gained traction in parliamentary discussions, such as the 1855 Commons debate on decimal coinage, where advocates like William Brown highlighted the mil's utility for precise bookkeeping, noting its value as slightly less than a farthing (approximately 0.24 old pence).[17] However, opposition arose over practical concerns, including the mil's awkward size for everyday transactions among the working class and potential disruption to the entrenched £sd (pounds, shillings, pence) system.[18] The government ultimately favored incremental changes, such as introducing the florin (one-tenth of a pound) in 1849, over a full mil-based overhaul. A subsequent Royal Commission on Decimal Coinage, established in 1856, further evaluated the idea in its preliminary report of 1857 and final report of 1859, concluding that while decimalization offered theoretical advantages for accounting, it was inadvisable due to incompatibility with existing weights, measures, and public customs.[18] As a result, the mill was never officially adopted as a circulating unit in the United Kingdom, and the traditional system persisted until decimalization in 1971, which instead divided the pound into 100 pence. Despite lacking formal status, the mill occasionally appeared in pre-1971 accounting ledgers as an informal unit equivalent to 1/1000 of a pound (or about 0.1 modern pence) for recording minute fractions in business and trade contexts, such as wholesale pricing or interest calculations, lingering into the early 20th century before fading with broader decimal reforms.[18] The unadopted UK proposals nonetheless influenced decimal experiments in Commonwealth territories, though domestic implementation remained elusive.[18]Malta
The mill (plural: mils) was the smallest unit of the Maltese lira (MTL), introduced upon the decimalisation of Malta's currency on 16 May 1972, when the Central Bank of Malta issued the first series of decimal coins.[42] One Maltese lira was equivalent to 100 cents or 1,000 mils, with each cent subdivided into 10 mils to facilitate precise financial transactions.[42] This structure stemmed from Malta's transition from the pre-decimal sterling-based system inherited from British colonial rule, adopting a "pound and mil" framework similar to that proposed in the United Kingdom but implemented locally.[42] Unlike higher denominations, no 1-mil coin was minted, but circulation coins of 2 mils, 3 mils, and 5 mils were produced in aluminium from 1972 to 1980, featuring designs such as the traditional Maltese lampstand on the 5-mil piece.[42] These low-value coins enabled retail pricing and accounting to the nearest mil, allowing for fine-grained cost expressions in everyday commerce, such as marking goods at prices like Lm 1.235 (or 1 lira, 23.5 cents).[43] The mil's notional use persisted in financial records and pricing mechanisms throughout the lira's circulation period, supporting accuracy in sectors like trade and taxation without the need for even smaller physical denominations.[42] The Maltese lira, and thus the mill, remained in use until Malta's accession to the eurozone. On 1 January 2008, the euro replaced the lira at the irrevocable fixed exchange rate of €1 = MTL 0.429300, effectively phasing out the mil as euro cent subdivisions took over for sub-unit precision.[44] Maltese lira coins, including the mil denominations, ceased to be legal tender on 31 January 2008, though they could be exchanged at the Central Bank until 1 February 2010.[44]Mandatory Palestine, Israel, and Jordan
During the British Mandate for Palestine, the Palestine pound was introduced as the official currency on November 1, 1927, by the Palestine Currency Board, which had been established in London the previous year to unify the disparate foreign currencies previously in circulation, such as Egyptian pounds and Ottoman coins.[21] The Palestine pound was pegged at par to the British pound sterling and subdivided into 1,000 mils, with coins issued in denominations including 1, 5, 10, 20, 50, and 100 mils, primarily in bronze and silver alloys, facilitating everyday banking, trade, and transactions across the region, including Transjordan.[45] By 1928, it became the sole legal tender, supporting economic activities in agriculture, commerce, and public administration under British oversight, with notes and coins bearing inscriptions in English, Arabic, and Hebrew to reflect the Mandate's multilingual administration.[21] Following the end of the Mandate on May 14, 1948, and the establishment of the State of Israel, the Palestine pound continued briefly in Israeli-controlled areas but was quickly supplanted by the Israeli pound (also known as the lira), which maintained the 1,000-subunit structure. The first Israeli coins, aluminum 25 mil pieces dated 5708 (1948 Hebrew calendar) and minted in limited quantities in Jerusalem and Holon, were issued on April 6, 1949, to address a shortage of small-denomination coins amid wartime disruptions.[46] These mil coins were short-lived, canceled by September 1950, as the subunit transitioned to the pruta in late 1948, with the first pruta-denominated coin—a 50 pruta piece—entering circulation on May 11, 1949, and the pruta series continuing until the 1950s when inflation and currency reforms led to its replacement by the agorot (1/100 lira) in 1960.[46] In the areas under Jordanian control after the 1948 Arab-Israeli War, including the West Bank following formal annexation in April 1950, the Palestine pound and its mil subdivision persisted briefly for local transactions until the introduction of the Jordanian dinar in 1949, which became legal tender across the kingdom and annexed territories by mid-1950. The dinar, equivalent to the Palestine pound in value at launch, was divided into 1,000 fils, evolving from the mil as a comparable minor unit to support continuity in trade and banking during the geopolitical transition, with mils phased out entirely by 1951 as Jordanian coins and notes, including fils denominations, took over. Today, neither the mil nor its direct successors in pruta or fils form are used in modern Israeli shekels or Jordanian dinars, though their historical role underscores the economic integration and fragmentation of pre-state Levantine economies under colonial and post-colonial influences.Hong Kong
In 1863, under British colonial administration, the Hong Kong dollar was officially subdivided into 1,000 mils, with bronze 1 mil coins introduced as the smallest physical denomination to facilitate minor transactions. These holed coins, minted at the Royal Mint in London and weighing approximately 1 gram with a 15 mm diameter, bore the portrait of Queen Victoria on the obverse and a Chinese junk ship on the reverse, reflecting a blend of imperial and local iconography. The issuance continued through 1866, aligning with the short operational period of the short-lived Hong Kong Mint established in 1866 at Causeway Bay.[47][48][49] The 1 mil coin's production ceased after 1866 primarily due to its impractically small size and limited utility in an economy where even basic items like a simple breakfast of congee and youtiao could cost around that value, making handling cumbersome amid rising prices. The Hong Kong Mint itself closed in 1868 after incurring significant losses of HK$440,000 from poor public reception of the new coinage, leading to reliance on foreign silver dollars and banknotes for circulation. No further mil coins were ever minted, marking one of the briefest physical issuances of the mill unit in any British colony.[48][47][50] Although physical coins were discontinued, the mil endured as a notional subdivision of the cent (1 cent = 10 mils) in accounting and legal contexts until economic inflation and decimalization practices rendered such fine divisions obsolete by the mid-20th century, when smaller bronze denominations were phased out. Today, surviving 1863–1866 examples are rare collector's items, valued for their historical significance in early colonial numismatics and often graded by services like NGC or PCGS for auction markets.[51][47]Cyprus
The mil, a subdivision of the Cypriot pound equivalent to 1/1,000 of the pound, was introduced in 1955 as part of the currency's decimalization under British administration. This reform replaced the pre-existing piastre-based system, in which 1 pound equaled 180 piastres, aligning the Cypriot pound more closely with modern decimal standards while maintaining parity with the British pound sterling until 1972. The change facilitated easier calculations in commerce and administration, reflecting broader imperial efforts to standardize currencies across colonies.[52][53] Throughout its circulation from 1955 to 1982, the mil enabled precise pricing in trade, banking, and retail transactions, allowing for fine-grained denominations in contracts, invoices, and accounting ledgers. Coins were minted in various mil values, including 1 mil (aluminum, issued 1963–1981), 5 mils (1955–1981), 25 mils (1955–1982), 50 mils (1955–1982), and 100 mils (1957–1982), primarily under the Royal Mint and later the Central Bank of Cyprus, using materials like aluminum bronze and copper-nickel for durability in everyday use. These coins circulated alongside banknotes for larger amounts, supporting economic activities during Cyprus's transition to independence in 1960 and subsequent development. The mil's role was particularly vital in the post-independence era, when the Central Bank of Cyprus assumed responsibility for monetary issuance in 1963.[54] By the early 1980s, persistent inflation had eroded the mil's practical value, rendering transactions in such small units inefficient and prompting a second decimal reform in 1983 that abolished the mil and redefined the pound as comprising 100 cents. This shift eliminated the need for sub-cent precision, streamlining pricing and reducing production costs for low-denomination coins. The Cypriot pound, now cent-based, remained in use until Cyprus joined the Eurozone on January 1, 2008, adopting the euro at a fixed rate of €1 = CYP 0.585274, with no revival of the mil or any thousandth subunit in the new system.[55][56]Tunisia and Egypt
The Tunisian dinar (TND), introduced on November 1, 1958, following Tunisia's independence from French colonial rule, is subdivided into 1,000 millimes (Arabic: ملّيم), a unit reflecting the decimal structure inherited from the preceding Tunisian franc system.[57][58] Millime coins were initially minted in denominations including 1, 2, and 5 millimes starting in 1960, facilitating small transactions in the post-independence economy.[59] However, the 1 millime coin was issued only in 1960 and quickly became obsolete, while the 2 millime coin's production ceased after 1983; both are no longer legal tender, with their discontinuation around 1985 marking a shift away from the smallest physical denominations due to inflation and reduced practical use.[59] Higher millime coins, such as 5 and 10 millimes, remain legal tender but are rarely circulated, persisting primarily as notional units in accounting and pricing.[60] In Egypt, the Egyptian pound (EGP), established in 1834 during the reign of Muhammad Ali Pasha, has historically been divided into 1,000 millièmes (Arabic: مليم), a subdivision tracing back to Ottoman influences on the currency system before formal decimalization.[61][62] The millième became explicitly defined in 1916 when the piastre—itself equivalent to 10 millièmes—was restructured under British administration, with 1 pound equaling 100 piastres or 1,000 millièmes to accommodate finer divisions in trade and daily commerce.[63] Small millième coins, including 1, 2, and 5 millièmes, were produced from the early 20th century until the 1980s, but production halted as inflation rendered them impractical; by the late 20th century, millièmes ceased to be legal tender, with the piastre also phased out in favor of larger denominations like the 25-piastre coin.[64] Today, the millième exists only notionally within the pound's structure for legacy financial records and historical references.[64] The term "millieme" or "millième" in both currencies derives from the Arabic adaptation of the French word for "thousandth," underscoring French colonial impact on Tunisia's monetary framework during the protectorate era (1881–1956) and indirect influences in Egypt through earlier Mediterranean trade and administrative practices.[58][63] Although physical millime and millième coins are largely obsolete in everyday use across both nations, the units endure in notional form for accounting precision and archival financial documentation, bridging historical Ottoman, colonial, and modern systems.[65][64]Related Units and Concepts
Similar Subdivisions in Global Currencies
The concept of a subunit equivalent to one-thousandth of a currency's main unit parallels the U.S. mill and appears in various global systems, often shaped by colonial influences from British, French, or Ottoman traditions rather than a universal standard. These thousandth divisions enable precise valuation in taxation, trade, and historical accounting, though their practical use varies by country and era, with some becoming obsolete as economies modernized. In French-influenced North African currencies, the term "millieme" or "millime" denotes such a subunit. The Egyptian pound (EGP) is subdivided into 100 piastres or 1,000 milliemes, where one millieme equals 0.001 EGP, facilitating detailed financial calculations despite the piastre's dominance in everyday transactions.[66] Similarly, the Tunisian dinar (TND) divides into 1,000 millimes, with coins issued in denominations like 5, 10, 20, 50, and 500 millimes to support small-scale commerce.[58] In Arab Gulf states, the Arabic "fils" (فلس) serves as a comparable thousandth subunit for dinar-based currencies under British colonial legacy. For instance, the Bahraini dinar (BHD) equals 1,000 fils, with circulating coins in 5, 10, 25, 50, and 100 fils to accommodate precise pricing in retail and services.[67] This structure extends to currencies like the Iraqi dinar, Jordanian dinar, and Kuwaiti dinar, each subdivided into 1,000 fils, though smaller fils denominations are increasingly rare in circulation due to inflation. In Latin America, the Spanish "centésimo" typically functions as a hundredth subunit (1/100) in currencies such as the Uruguayan peso (UYU), which divides into 100 centésimos, rather than a thousandth, reflecting metric-inspired but not always finer divisions. Historical European examples include the Portuguese mil-réis, an obsolete unit used until 1911, subdivided into 1,000 réis, where the réis acted as the thousandth equivalent for everyday transactions in Portugal and its colonies.[68]| Currency | Main Unit | Thousandth Subunit | Equivalent Value | Notes |
