Gold dinar of Umayyad Caliph Abd al-Malik ibn Marwan, minted at Damascus, Syria in AH 75 (697/698 CE), having a weight of almost 1 mithqāl (5 grams)

Mithqāl (Arabic: مثقال, romanizedmiṯqāl) is a unit of mass equal to 4.25 grams (0.137 ozt) which is mostly used for measuring precious metals, such as gold, and other commodities, like saffron.

The name was also applied as an alternative term for the gold dinar, a coin that was used throughout much of the Islamic world from the 8th century onward and survived in parts of Africa until the 19th century.[1] The name of Mozambique's currency since 1980, the metical, is derived from mithqāl.[2]

Etymology

[edit]

The word mithqāl (Arabic: مثقال; “weight, unit of weight”) comes from the Arabic thaqala (ثقل), meaning “to weigh” (cf. Hebrew: שקל, romanizedshekel). Other variants of the unit in English include miskal (from Persian or Urdu مثقال; misqāl), mithkal, mitkal and mitqal.

Indian mithqaal

[edit]

In India, the measurement is known as mithqaal. It contains 4 mashas and 3½ raties (rata'ii; مثقال).[3]

It is equivalent to 4.25 grams when measuring gold,[4] or 4.5 grams when measuring commodities.[5] It may be more or less than this.[6]

Nikki mithqal

[edit]

A gold coin minted in Nikki, Benin and known as the mithqal was in wide circulation in West Africa in the 18th century, particularly the Niger bend. It was useable in the trans-Saharan trade and coexisted with the use of cowries as shell money.[7]

The mithqāl (Arabic: مثقال) is a traditional unit of mass originating in the Islamic world, primarily used for weighing precious metals such as and silver, with a standard value of approximately 4.25 grams established during the Umayyad Caliphate's coinage reforms in the late CE. This unit derives its name from the Arabic term for "weight," reflecting its foundational role in early Islamic , where it corresponded to the mass of the dinar coin, a key element in monetary and trade systems across the caliphates. Historically, the mithqāl traces its roots to pre-Islamic Arabian practices influenced by Byzantine and Sasanian weight standards, with the Prophet Muhammad standardizing measurements based on systems prevalent in Makkah and Madinah for fair trade. By the 8th century, it became integral to Islamic coinage issued in Damascus, evolving from a general term for weight into a specific standard that facilitated commerce along trans-Saharan and Mediterranean routes. In religious and legal contexts, such as the calculation of zakat (obligatory alms), the mithqāl-based nisab threshold required 20 dinars (about 85 grams of gold) or 200 dirhams of silver, underscoring its enduring influence on Islamic jurisprudence and economics. Despite its standardization, the mithqāl exhibited significant regional and temporal variations, particularly in 19th-century West and , where local adaptations for led to weights ranging from as low as 1.5–2 grams in Ashanti (due to gold dust ) to about 4.5 grams in and 4.5–4.7 grams in and . These differences arose from practical needs in diverse economic environments, including gold dust in and minted coins in , yet the unit remained a common reference for exchange rates and pricing among travelers and merchants. By the , the mithqāl has largely been supplanted by metric systems but persists in cultural, numismatic, and religious discussions of Islamic heritage.

Definition and Characteristics

Standard Measurement

The mithqal is an unit of mass primarily employed for weighing precious metals such as and commodities including , with its classical value standardized at approximately 4.25 grams (0.137 troy ounces). This measurement derives from Islamic metrological traditions, where the mithqal equates to 24 nakhuds, smaller units based on the weight of seeds, each nakhud historically approximating 0.177 grams to yield the total of 4.25 grams. Historical records indicate minor variations in the mithqal's application, such as 4.25 grams specifically for and silver versus up to 4.5 grams for other goods like spices or textiles, reflecting regional adjustments in weighing practices. These differences arose from practical in trade contexts but were generally resolved to the 4.25-gram standard for in authoritative Islamic sources, ensuring consistency in monetary and commercial transactions.

Primary Applications

The mithqal served as a fundamental unit for weighing precious metals and select commodities in Islamic commerce, particularly gold, silver, and saffron, beginning from the 8th century with the establishment of standardized Islamic coinage and trade networks across the Middle East, North Africa, and beyond. In trans-Saharan and Mediterranean trade routes, merchants relied on the mithqal to quantify gold dust and ingots, ensuring consistent valuation in bustling markets like those in Cairo and Baghdad, where it facilitated exchanges between Arab, Byzantine, and Persian traders. Similarly, silver was measured in mithqals for minting dirhams and settling debts, while saffron—a high-value spice from regions like Khorasan—was traded by this weight due to its delicacy and expense, with records indicating one mithqal of saffron fetching up to 20 dinars in 12th-century Iranian markets. The mithqal also functioned as an alternative designation for the gold dinar coin, which was minted to exactly one mithqal in weight, approximately 4.25 grams, thereby intertwining the unit with monetary systems for both weighing and currency purposes. This equivalence streamlined transactions in Islamic economies, where the dinar-mithqal served as a stable medium of exchange, accepted from the Umayyad Caliphate onward for everything from royal tributes to international payments. By equating the coin's mass directly to the weight unit, it minimized discrepancies in trade, promoting trust in cross-regional dealings without needing separate scales for valuation. In everyday commerce across the , the mithqal remained a practical tool for weighing until the , even as European influences introduced metric alternatives. In markets such as Tripoli's souks and Timbuktu's exchanges, vendors used portable balances calibrated to mithqals for routine of jewelry, spices, and , allowing small-scale artisans and itinerant traders to conduct precise, localized business amid fluctuating supplies from West African mines. This persistence highlighted its adaptability in informal economies, where it outlasted formal coinage reforms but gradually faded with colonial standardization in the late 1800s.

Etymology and Historical Origins

Linguistic Derivation

The term mithqāl (مِثْقَال) originates from , derived from the verbal root thaqala (ثَقَلَ), which means "to weigh" or "to be heavy." This root conveys the concept of weight or heaviness, and the noun mithqāl specifically denotes "a weight," "unit of weight," or "that which is weighed," often in the context of measuring precious metals or commodities. In scholarly systems, such as those based on the International Journal of Middle East Studies (IJMES) or standards, the term is transcribed as miṯqāl, preserving the emphatic /θ/ (represented as ṯ) and the uvular stop /q/. Historical European texts, particularly from medieval and early modern periods dealing with Islamic trade and , exhibit variant spellings adapted to Latin alphabets, including miskal, mithkal, mitkal, and mitqal. These variations arise from phonetic approximations, where the Arabic /θ/ is often rendered as /t/ or /s/, and /q/ as /k/ or /q/, influenced by the transcribers' native languages. The term spread to other Islamic languages through cultural and commercial exchanges, influencing related vocabulary in Persian and Turkish. In Persian, it appears as misqāl or mazqāl (مِثْقَال), retaining much of the original form but with occasional vowel shifts for ease of pronunciation. In , it is borrowed as miskal (مِثْقَال), featuring a phonetic shift from Arabic /θ/ to /s/, a common adaptation in lacking the emphatic , while the plural form misākil reflects plural patterns.

Early Development and Adoption

The mithqal originated as a standardized weight unit in the during the early CE, primarily for measuring the and replacing the inconsistent Byzantine solidus and Sassanid drachm systems that had circulated in conquered territories. Caliph enacted key minting reforms in 77 AH (696/697 CE), issuing the first aniconic Islamic dinars from at precisely 4.25 grams, aligning with the Hijazi mithqal standard of 4.25 grams used in and , which was derived from pre-Islamic trade practices involving 72 grains (habbah). This standardization, influenced by earlier adjustments under Caliph but formalized under Abd al-Malik, ensured uniformity for taxation, , and commerce across the expanding empire, with the weighing exactly one mithqal to promote . The mithqal's adoption extended into the Abbasid Empire following its establishment in 750 CE, where it became integral to the vast medieval Islamic trade networks spanning from the Mediterranean to the . Abbasid caliphs maintained the Umayyad weight of 4.25 grams for the , as evidenced by official glass weights from the Abbasid period, which facilitated precise transactions in gold and silver across Baghdad's markets and beyond. This continuity supported the empire's economic prosperity, with the mithqal serving as a benchmark for weighing precious metals in international exchanges. Historical evidence from 9th- to 12th-century Abbasid texts underscores the mithqal's entrenched role in fiscal and legal systems. Abu Ubayd al-Qasim ibn Sallam's Kitab al-Amwal (written ca. 838 CE) details the mithqal's specifications in relation to dirhams and its application in state revenues, reflecting its standardization for equitable trade. Similarly, al-Mawardi's 11th-century legal compendium Al-Ahkam al-Sultaniyya references the mithqal as the canonical unit for in caliphal decrees, highlighting its adoption in administrative reforms that bolstered the empire's commercial networks. These texts illustrate how the mithqal evolved from a Umayyad into a cornerstone of Abbasid .

Regional and Historical Variations

Indian Mithqal

The Indian mithqal emerged as an adapted weight unit in the subcontinent during the from the 16th to 19th centuries, primarily through trade networks that incorporated Islamic measurement practices. It played a central role in , especially for valuing in jewelry production and weighing high-value commodities like spices in markets across regions such as and . This adaptation reflected the empire's efforts to standardize transactions in artisanal and mercantile sectors, where precision was essential for gems, , and exotic goods exchanged along overland and maritime routes. In the Indian context, the mithqal was equivalent to 26 s (from seeds), aligning with local subdivisions derived from seed-based units like the rati. For , it measured 4.25 grams, while for commodities such as spices or medicines, it was set at 4.5 grams to account for practical variations in density and handling. These specifications, detailed in Mughal administrative texts like the , ensured consistency in imperial workshops and bazaars. Unlike the more uniform Arabic mithqal of approximately 4.27 grams used across the , the Indian variant incorporated regional nuances, such as alignment with the tola (roughly 11.66 grams, equivalent to about 2.75 mithqals for ), which facilitated broader scaling in everyday trade and taxation. This integration allowed the mithqal to coexist with indigenous systems, enhancing its utility in diverse economic activities without fully supplanting local traditions.

Nikki Mithqal

The Nikki mithqal was a stamped minted in the kingdom of Nikki, located in present-day , during the early . Weighing approximately one mithqal—the traditional Islamic unit of weight for , equivalent to roughly 4.25 grams—this served as a standardized in the region rather than being individually weighed for each transaction. In the Nikki kingdom's economy, the coin facilitated protection of trade routes and treaties with neighboring states, circulating widely across West African trans-Saharan networks, especially around the bend. It was commonly exchanged alongside shells for high-value goods, integrating into broader systems that linked Nikki to empires like Asante. The Nikki mithqal's use declined in the late 19th and early 20th centuries with the spread of European colonial currencies in West Africa.

Other Middle Eastern and African Forms

In the Ottoman Empire, rabbinical records from 17th-century Egypt reference the "mithqal of Tebriz" at 4.608 grams as a weight standard for coin valuation. Such measurements ensured consistency in the empire's extensive Mediterranean and overland trade networks. North African adaptations of the mithqal persisted prominently in and until the onset of French in the , integrating with regional dirham-based systems for and silver dealings. In 19th-century , the mithqal served as a weight standard of around 4.25 grams for silver in trade and taxation. Algerian usage mirrored this, with the mithqal tied to the dirham (subdivided into 20 qirats) for trans-Saharan imports, often valued at 4.68 grams in 19th-century trade records before French forces disrupted local minting in 1830. These forms emphasized the unit's role in linking North African economies to Islamic monetary standards, where 10 dirhams approximated 7 mithqals for balanced exchanges. Beyond the Nikki region, sub-Saharan extensions of the mithqal appeared in Mali's trade networks from the medieval period onward, where it measured dust and nuggets amid local weight discrepancies. In 19th-century accounts of Malian commerce, the mithqal hovered around 4.5 grams as a benchmark for trans-Saharan exports, but local variations arose due to regional differences and the challenges of weighing fine powder. These adaptations highlighted the unit's flexibility in sustaining Mali's pivotal role in West African flows, despite inconsistencies that complicated standardization across Sahelian markets.

Equivalents and Conversions

Relations to Contemporary Units

The mithqal, as a traditional unit of primarily for precious metals, equates to 4.25 grams in the , approximately 0.13664 ounces (used for and silver), 0.14991 avoirdupois ounces, and 65.5875 grains. These conversions stem from the historical of the mithqal to 4.25 grams, aligning with its use in Islamic coinage and trade weights.

For modern applications, the mass in grams can be calculated using the equation m=n×4.25m = n \times 4.25, where mm is the in grams and nn is the number of mithqāls. This factor derives from the mithqal's historical basis in 72 grains, with the standardized at approximately 0.059027 grams (yielding 72×0.0590274.2572 \times 0.059027 \approx 4.25 grams after adjustments for precision in medieval ). In the Baháʼí Faith, the mithqāl variant differs, defined as 19 nakhuds to align with specifications in the Bayán. The calculation proceeds as follows: 24 nakhuds equal 4.6 grams (4 and three-fifths grams), so one nakhud is 4.6/24=0.19164.6 / 24 = 0.191\overline{6} grams; thus, one mithqāl is 19×0.1916=3.641619 \times 0.191\overline{6} = 3.641\overline{6} grams, commonly rounded to 3.642 grams. This yields nine mithqāls at 32.775 grams or 1.05374 troy ounces. The mithqal shares a 1:1 weight equivalence with the historical gold dinar. The mithqal functioned as the primary weight standard for the gold dinar in early Islamic monetary systems, where one dinar was equivalent to one mithqal by weight, ensuring consistency in precious metal valuation across trade networks. This equivalence underscored the mithqal's role in stabilizing the dinar against fluctuations in pre-existing coinage. In relation to the silver dirham, the mithqal maintained a fixed ratio of 7:10 by weight, meaning one dirham equaled seven-tenths of a mithqal—with the dirham weighing approximately 2.975 grams—or equivalently, ten dirhams matched seven mithqals; this proportion, rooted in classical Islamic jurisprudence, facilitated balanced bimetallic exchange and prevented arbitrage. The mithqal's standardization reflected influences from pre-Islamic units, particularly the Byzantine solidus, a gold coin weighing approximately 4.5 grams that early Muslims adopted and adapted during the Umayyad period (661–750 CE), reducing it slightly to 4.25 grams to align with the established Arabic mithqal for purer Islamic coinage free of figural imagery. This shift marked a transition from Byzantine imitation to an independent standard, enhancing economic sovereignty while preserving compatibility with Mediterranean trade. The dirham's lineage traces to the Sassanid drachma, linking the mithqal's silver counterpart to pre-Islamic Persian . The mithqal's internal structure featured a hierarchical subdivision for precise in and minting: one mithqal equaled 24 nakhuds, with each nakhud further divided into 3 habbahs, yielding 72 habbahs per mithqal overall; this granular allowed for accurate apportionment of gold dust or filings in transactions. This subdivision hierarchy not only supported the dinar's integrity but also paralleled fractional divisions in related units like the , which was divided into 6 daniqs, or further into 10 qirats (each 3 habbahs) and 50.4 habbahs overall, promoting reliability in diverse economic contexts. For scale, the mithqal equates to about 4.25 grams today.

Legacy and Cultural Impact

Influence on Modern Currencies

The metical, Mozambique's official currency since its introduction in 1980, derives its name directly from the term mithqāl, a historical unit of weight for that symbolized the extensive trade networks influencing East African commerce during the medieval and early modern periods. This etymological link acknowledges the region's longstanding connections to routes where merchants exchanged gold dinars, often measured in mithqāls, for local goods like and slaves. The choice of name for the metical underscores a deliberate nod to this heritage amid post-independence efforts to foster tied to . Although largely supplanted by metric grams in formal trade, the mithqāl persists in informal gold markets across parts of the as of 2025, particularly in where variants like the mithqāl (3.456 grams), sarrafi mithqāl (4.608 grams), and common mithqāl (4.6875 grams) are referenced for raw 24-karat . In the Iranian market, the quoted mazneh price per mithqāl of 24-karat gold can be used to calculate the price of 18-karat gold per gram with the formula: 18-karat gold per gram = mazneh × 0.75 ÷ 4.608; this derives from adjusting for purity (18/24 = 0.75) and the gram-to-mithqāl conversion (1 mithqāl ≈ 4.608 grams), providing the base price without premiums or fees. These traditional units facilitate negotiations in local bazaars, bridging historical practices with contemporary transactions amid fluctuating international prices. In African contexts, while direct usage has waned, echoes of the mithqāl influence informal dealings through cultural memory of gold weighing in regions like , though modern markets predominantly adopt grams.

Usage in Trade and Religion

The mithqal served as a fundamental unit in the trans-Saharan gold trade from the 8th to the 19th centuries, standardizing the weighing of gold dust exchanged for salt, slaves, and other commodities across West and North Africa. Derived from earlier Roman and Byzantine metrological systems, it enabled consistent valuation in caravan routes linking Saharan oases to Mediterranean ports, with archaeological evidence of weights confirming its adoption by Arab traders post-conquest. By the 19th century, travelers documented its persistent use in markets like Timbuktu and Ashanti, where local variations still facilitated bulk gold transactions despite fluctuating regional standards. In the networks spanning the same period, the mithqal underpinned the gold , a coin weighing one mithqal, which and merchants employed for exchanges of gold with spices, textiles, and aromatics from and . This standardization supported maritime voyages from the Persian Gulf to Malabar ports, where 11th–12th-century records note Egyptian mithqal-weighted gold pieces as currency in spice-laden deals, promoting across Islamic commercial spheres. Religiously, the mithqal holds scriptural significance in Islamic practices, particularly for calculations, where hadiths establish the threshold at 20 mithqal of (approximately 85 grams), obligating 2.5% on holdings exceeding this after one lunar year. This benchmark, derived from prophetic traditions, ensures equitable distribution, with equivalent silver measures at 200 dirhams for broader accessibility. In pilgrimage contexts, hadiths reference mithqal weights for valuing offerings and charitable distributions, such as silver limits in items to maintain without ostentation. Culturally, the mithqal symbolizes precision and abundance in medieval , often evoking weighed treasures in that extol and divine bounty, as in anthologies describing poetic rewards or opulent hoards measured to the exact mithqal. This imagery underscores themes of measured prosperity in works blending motifs with reflection.
