from Wikipedia

A lakh (/læk, lɑːk/; abbreviated L; sometimes written lac[1]) is a unit in the Indian numbering system equal to one hundred thousand (100,000; scientific notation: 105).[1][2] In the Indian 2, 2, 3 convention of digit grouping, it is written as 1,00,000.[3] For example, in India, 150,000 rupees becomes 1.5 lakh rupees, written as 1,50,000 or INR 1,50,000.

It is widely used both in official and other contexts in Afghanistan, Bangladesh, Bhutan, India, Myanmar, Nepal, Pakistan, and Sri Lanka. It is often used in Bangladeshi, Indian, Pakistani, and Sri Lankan English.

Usage

[edit]

In Indian English, the word is used both as an attributive and non-attributive noun with either an unmarked or marked ("-s") plural, respectively. For example: "1 lakh people"; "lakhs of people"; "20 lakh rupees"; "lakhs of rupees". In the abbreviated form, usage such as "5L" or "5 lac" (for "5 lakh rupees") is common.[4] In this system of numeration, 100 lakh is called one crore[3] and is equal to 10 million.

Formal written publications in English in India tend to use lakh/crore for Indian currency and Western numbering for foreign currencies, such as dollars and pounds.[5]

Silver market

[edit]

The term is also used in the pricing of silver on the international precious metals market, where one lakh equals 100,000 troy ounces (3,110 kilograms) of silver.[6][7]

Etymology and regional variants

[edit]

The modern word lakh derives from Sanskrit: लक्ष, romanizedlakṣa, originally denoting "mark, target, stake in gambling", but also used as the numeral for "100,000" in Gupta-era Classical Sanskrit (Yājñavalkya Smṛti, Harivaṃśa).[8]

A lakh (also spelled lac; abbreviated as L) is a unit in the South Asian numbering system equal to one hundred thousand ( or 10⁵). It is commonly used to denote large quantities, especially in financial and statistical contexts, such as salaries, populations, or currency amounts in rupees. The term originates from the Hindi lākh, which traces back to the Sanskrit lakṣa, originally meaning "sign," "mark," or "target" (as in a gambling stake), evolving to represent the numerical value of 100,000 in ancient texts. Borrowed into English via colonial trade and administration in the early 17th century, its earliest recorded use appears in 1613 in writings by English travel writer Samuel Purchas, reflecting British encounters with Indian commerce. In pronunciation, it varies regionally: /lɑːk/ or /læk/ in British and American English, and /laːkʰ/ in Indian English. Within the —distinct from the Western short scale—digits are grouped as three (thousands), followed by pairs (ten thousands, lakhs, crores), facilitating the expression of large figures; for example, 1,23,45,678 is read as "one crore twenty-three lakh forty-five thousand six hundred seventy-eight." The lakh remains integral to official documents, media, and daily discourse across , including India, Pakistan, Bangladesh, , , , and , where it simplifies reporting vast scales like national budgets or cases (e.g., "over 2 lakh cases"). Occasionally, it denotes an indefinitely large number, as in "lakh of people," emphasizing abundance.

Definition and Notation

Numerical Value

The lakh is a unit in the South Asian numbering system equivalent to exactly 100,000 (or 10510^5) in the international decimal system. It serves as a fundamental grouping for expressing large quantities, representing 100 thousands. In the hierarchical structure of the South Asian system, the lakh occupies a central position between smaller units like the thousand (10310^3) and larger ones such as the crore (10710^7 or 10 million, equivalent to 100 lakh). This scale facilitates the notation of very large numbers by grouping digits in periods of three (for units to thousands) followed by pairs (for lakhs and above), distinguishing it from the Western system's consistent triads. The system extends beyond the crore to accommodate even greater magnitudes, with the lakh fitting into the progression as follows:
UnitNumerical ValueRelation to Lakh
Thousand10310^30.01 lakh
Lakh10510^51 lakh
10710^7100 lakh
10910^910,000 lakh
Kharab101110^{11}1,000,000 lakh
This hierarchy, while rooted in ancient traditions, aligns with the decimal base to ensure compatibility with global mathematical standards.

Written and Spoken Forms

In the , the lakh—equivalent to 100,000—is denoted with commas placed after every two digits from the right, beginning after the thousands place, resulting in the form 1,00,000. This convention aligns with the broader structure that groups digits in sets of two for units beyond thousands, such as lakhs and crores, to facilitate readability in South Asian contexts. In contrast, the Western or international numbering system employs commas every three digits from the right, rendering the same value as 100,000. This divergence stems from differing place-value groupings, with the Indian system emphasizing pairs after the three digits (units, tens, , thousands). Such variations in comma placement can create ambiguities in international communications, particularly in financial or technical documents where numerical precision is essential. To mitigate this, style guides and international standards recommend explicitly using the term "lakh" in textual descriptions alongside numerals, or converting to the international system for global audiences, ensuring unambiguous conveyance of magnitude. In spoken form, "lakh" is typically pronounced as /lɑːk/ in , with a long 'a' sound akin to "lack" but elongated, while in it is /lak/ and in /lɑk/. This pronunciation integrates seamlessly into everyday phrases, such as "ten lakh rupees" to denote one million rupees, reflecting its common usage in verbal transactions and media across . Phonetic guides like those in major dictionaries aid non-native speakers in adopting the correct articulation for clarity in multicultural settings. Abbreviations for lakh include "L" in formal notations, as seen in financial ledgers, while "lac" serves as an alternative spelling in some documents, though the officially prefers "lakh" in English-language communications, such as on cheques and reports, to standardize terminology and avoid spelling discrepancies. This preference is evident in RBI guidelines and usage (as of 2024).

Historical Development

Origins in Ancient Systems

The lakṣa unit, signifying , first emerged within the Vedic corpus (c. 1500–500 BCE) as an integral component of numeral systems designed to quantify vast aggregates in astronomical computations and elaborate sacrifices. These early formulations reflected a cultural emphasis on conceptualizing immense scales, essential for describing cosmic cycles and sacrificial offerings that involved counting multitudes of items or time spans. References to lakṣa appear in foundational texts, including the and subsequent Vedic saṃhitās such as the Yajurveda-saṃhitā and Taittirīya-saṃhitā, where it denotes the sixth power of ten in hierarchical enumerations extending to parārdha (10¹²). This usage underscores the Vedic tradition's sophistication in handling large magnitudes without , relying instead on verbal multipliers for precision in liturgical and calendrical contexts. Later integrations occur in , notably the Anuyogadvāra-sūtra (c. 300 BCE), which employs lakṣa amid expansive cosmological models, and in Buddhist scriptures like ’s Abhidharmakośa (c. 4th–5th century CE, drawing on earlier traditions), positioning it as the sixth denomination in systematic classifications of phenomena. The Brahmi numeral system (c. BCE) marked a pivotal advancement by introducing symbols for units up to thousands and higher powers, enabling the practical inscription and manipulation of large values like lakṣa through proto-positional arrangements on ashoka-era edicts and inscriptions. This graphical evolution supported the transcription of verbal large-number systems into durable records, bridging oral Vedic traditions with written administration. In administrative treatises such as Kauṭilya's Arthaśāstra (c. 300 BCE), lakṣa-like units facilitated the of revenues, with references to aggregates of in taxation frameworks and trade regulations, illustrating its role in state fiscal mechanisms. These applications highlight how ancient numeral practices extended from abstraction to pragmatic , laying groundwork for subsequent refinements.

Evolution in South Asia

During the Mughal era from the 16th to 19th centuries, the lakh became a standard unit in Persian-influenced administrative systems across , particularly for recording revenue, tributes, and expenditures in large quantities. Mughal rulers, drawing on Persian fiscal traditions that incorporated Sanskrit-derived terms, routinely employed lakh in official documents to denote 100,000 units of currency or goods, facilitating the management of vast empires where annual land revenue could reach tens of lakhs of rupees. For instance, administrative records under emperors like and detailed payments such as one lakh tolas of valued at 14 lakhs of rupees for provincial and military upkeep, embedding the term deeply into bureaucratic practices. Under British colonial rule, the lakh persisted in Anglo-Indian despite tensions with the imperial pound-shilling-pence system, serving as a practical tool for local transactions and record-keeping in rupees. While the and later the imposed sterling-based accounting for international trade and remittances to , Indian merchants and regional administrations retained lakh for domestic economic activities, such as collections and market dealings, to bridge traditional practices with colonial oversight. This duality created conflicts, as seen in when the introduction of English education via Macaulay's Minute emphasized Western curricula but still referenced lakh in fiscal discussions, like allocating "this lakh of rupees" for educational revival, highlighting its entrenched role even in English-language policy documents. Post-1947, the lakh was affirmed in standardized economic frameworks across newly independent nations, aligning with metric-influenced systems while preserving traditional numbering for clarity in large-scale data. In , the Indian Coinage Act of 1955, effective from 1957, decimalized the into 100 paise but retained lakh and in official economic reporting to accommodate South Asian conventions, as evidenced in national budgets and documents that expressed outlays like the First Five-Year Plan's 2,069 rupees (206,900 lakh rupees) in familiar units. Similar adoptions occurred in and , where the inherited continued in post-partition economies, with lakh used in statistical compilations for , trade, and GDP estimates to ensure continuity from colonial-era records. The 1950s economic reforms, including the , further promoted lakh in national statistics by integrating it into five-year plans' resource allocations, such as investments totaling several lakhs of rupees, to support centralized and public comprehension.

Modern Usage

In Finance and Commerce

In , particularly , the lakh serves as a fundamental unit for expressing monetary values in the (INR), facilitating clear communication in everyday financial transactions such as salaries, property deals, and stock valuations. For instance, average annual salaries in urban sectors are often quoted in lakhs, with entry-level professionals earning between 3 to 6 lakhs INR, while senior executives may command 50 lakhs or more. In the , share prices are denominated per unit but imply lakh-scale impacts on ; Limited achieved a historic milestone by reaching a of 20 lakh INR in 2024, underscoring the term's role in scaling corporate valuations for investors and analysts. The lakh also plays a key role in commodity markets, where it denotes large quantities of precious metals like and silver, both historically and in contemporary trading. During the Mughal era, significant trade and tribute payments involved measurements in lakh tolas—a tola being approximately 11.66 grams—to standardize bulk exchanges in bullion commerce. In modern Indian commodity exchanges like the (MCX), prices are routinely expressed in lakhs; as of November 2025, gold futures traded at around 1.27 lakh INR per 10 grams, and silver at 1.70 lakh INR per , reflecting the unit's practicality for high-value trades amid global volatility. In banking and finance, the lakh forms the base for structuring loans, interest rates, and budgetary allocations, enabling precise denomination of mid-to-large-scale financial instruments. have written off loans totaling 12.08 lakh INR since 2016, highlighting its use in aggregating non-performing assets for regulatory reporting. Government budgets frequently employ the lakh for targeted schemes; the Union Budget 2025-26 enhanced the loan limit under the Modified Subvention Scheme from 3 lakh to 5 lakh INR for farmers via Kisan Cards, supporting over 7.7 beneficiaries with short-term credit. Additionally, interest-free loans to states reached 1.11 lakh INR by early 2025, illustrating the unit's integration into fiscal planning and disbursement mechanisms. For international trade, the lakh is prevalent in remittances and export reporting within South Asia, often converted to millions for global audiences but retained domestically for accuracy. India received approximately 129.1 billion USD in remittances in 2024—equivalent to over 10,800 lakh crore INR—predominantly channeled through formal banking channels where inflows are capped or tracked in lakh units per transaction under RBI guidelines. In exports, merchandise trade data from the Ministry of Commerce uses lakhs for granular breakdowns; for April-December 2024, exports totaled 321.71 billion USD, or roughly 26,900 lakh crore INR, with the lakh aiding in sector-specific allocations like gems and jewelry, which rely on lakh-scale bullion imports. These practices ensure seamless conversions in cross-border commerce while aligning with international standards like USD millions in World Bank reports. In Pakistan and Bangladesh, similar usage appears in financial reporting, such as Pakistan's federal budget allocating funds in lakh rupees for development projects and Bangladesh citing lakh-scale remittances in economic surveys.

In Demographics and Statistics

The lakh unit is commonly employed in Indian census reporting to express population figures at state, district, and sub-district levels, facilitating clear comprehension of large-scale demographic data. For instance, the 2011 Census of India recorded Uttar Pradesh's total population as 199,812,341, equivalent to 19.98 crore or 1,998 lakh, underscoring its status as the most populous state. Similarly, district-level data often uses lakhs; Mumbai City District had a population of 3,085,411 (30.85 lakh), while Mumbai Suburban District reported 9,356,962 (93.57 lakh), contributing to the broader Mumbai Urban Agglomeration's scale. This notation aligns with official publications from the Office of the Registrar General & Census Commissioner, enabling precise breakdowns without cumbersome decimal places. In national statistics, bodies like the National Statistical Office (formerly NSSO) under the Ministry of Statistics and Programme Implementation (MoSPI) utilize the lakh for per capita metrics and incidence rates, particularly in surveys on social consumption and health. For example, the Household Social Consumption on Health Survey (75th round, 2017-18) reported morbidity rates as 12,431 persons per lakh population, highlighting variations across rural and urban areas. Educational attainment indicators, such as the number of colleges per lakh population, rose from 25 in 2011-12 to 30 in 2019-20, as per MoSPI's statistical profiles, reflecting infrastructural growth in higher education. These per-lakh normalizations provide standardized benchmarks for policy analysis, avoiding the need for percentages in absolute counts. Urban planning documents frequently express city and district populations in lakhs to assess , infrastructure needs, and . In , for instance, the (BMC) uses lakh-based figures for ward-level planning, noting the city's core districts exceed 120 lakh residents collectively, which informs and projections. Nationally, the Ministry of Housing and Urban Affairs incorporates lakh notations in reports like the Directory, where populations like those in emerging urban clusters (e.g., 5-10 lakh range) guide zoning and development schemes under programs such as AMRUT. Health and education metrics routinely apply "per lakh" for incidence and access rates in official bulletins, emphasizing outcomes. The Ministry of Health and Family Welfare's updates, disseminated via (PIB), tracked cases as low as 7.1 per lakh in early 2020, rising to over 30 per lakh by mid-year, aiding in containment strategies. Similarly, tuberculosis notifications under the National TB Elimination Programme declined from 237 to 195 cases per lakh between 2015 and 2023, as reported in 2025 health releases. In , the Unified District Information System for Education (UDISE+) reports teacher availability, such as 45 per lakh school-age children in certain states, supporting equity assessments. These metrics establish critical scales for interventions without delving into raw totals.

Etymology and Regional Variations

Linguistic Origins

The term "lakh" derives from the word lakṣa (लक्ष), which originally signified a "," "mark," or "target," and later extended to denote the numerical value of , with its earliest attestation in the referring to a "" in dicing contexts. This root word, from the verbal base lakṣ meaning "to mark" or "observe," reflects a conceptual link between enumeration and symbolic notation in ancient Indian linguistics. In Middle Indo-Aryan languages, lakṣa evolved into forms like lakkha in and , appearing in ancient Buddhist and Jain texts to represent both literal marks and the quantity 100,000, facilitating its transmission through and religious scriptures. These adaptations simplified the aspirated and retroflex sounds of classical , embedding the term in everyday and scholarly discourse across northern and by the early centuries CE. During the period of Islamic rule in , particularly under the and , the word was adopted into Persian as lak (لک), serving as an administrative term in fiscal records and entering Urdu as lākh (لاکھ) through Perso-Arabic script influences in official languages. This integration occurred as Persian became the of from the 13th century onward, propagating the term via court documents, trade ledgers, and multicultural exchanges. Phonetically, the term underwent shifts from the pronunciation /ˈlək.ʂə/—featuring a retroflex and schwa —to the Prakrit-Pali /ˈlək.kʰə/, and further to the modern Hindi-Urdu /lɑːkʰ/, simplifying the while retaining the core quality; in English loanwords, it is typically rendered as /læk/ or /lɑːk/, aligning with anglicized simplifications in colonial-era texts. The numerical value of remains intrinsically tied to this linguistic lineage.

Variants Across Languages and Regions

In and , the term for lakh is spelled लाख (lākh) in the Devanagari script for Hindi and لاکھ (lākh) in the script for Urdu, maintaining a consistent across both languages. In Nepali, it is spelled लाख (lākh), similar to Hindi. In Bengali, it is written as লাখ (lākh), with a pronunciation of /lækʰ/ or /lax/, though an alternative form লক্ষ (lokkho) is occasionally used in more formal or Sanskrit-influenced contexts. The Tamil equivalent is இலட்சம் (ilaṭcam), reflecting a Dravidian adaptation of the concept. In Telugu, it appears as లక్ష (lakṣha), closely aligned with Sanskrit-derived forms in other . In and , where English serves as an official language in administrative and financial contexts, the term is retained as "lakh" in Roman script for formal documents and publications, while local scripts such as (لاکھ) in and Bengali (লাখ) in are used in vernacular settings. Among South Asian diaspora communities, adaptations include the use of "lakh" in , as in ek lakh for one hundred thousand.

Comparisons with Other Numbering Systems

With International Systems

The lakh, defined as 100,000 or 10510^5, stands in contrast to the international short scale numbering system predominantly used in English-speaking countries, where one million equals 1,000,000 or 10610^6, corresponding to precisely 10 lakhs. This difference arises because the short scale increments names for powers of ten every thousand, whereas the lakh fits into the Indian system's grouping every hundred thousand. In the long scale system, historically employed in parts of and some scientific contexts, one milliard represents 10910^9, equivalent to 10,000 lakhs, as it multiplies the million (10610^6) by another thousand. In global finance and , the lakh's use can lead to misinterpretations when from South Asian contexts is shared internationally without conversion, potentially causing errors in economic analyses or investment decisions. For instance, reports originating from may cite figures in lakhs, which, if not translated, could be mistaken for smaller amounts under Western conventions, affecting cross-border trade evaluations or aid allocations. To mitigate this, international bodies routinely convert such figures; the , in its socioeconomic compilations involving Indian statistics, standardizes by expressing lakh-based values in millions for global comparability. Standardization efforts in international documentation emphasize clarity by retaining regional units like the lakh while providing explicit equivalents, particularly in scientific and financial publications. A practical example appears in World Bank reports on South Asian economies, where amounts such as "5 lakh" are translated as "500,000" or "0.5 million" to enhance accessibility for non-regional audiences.

With Other South Asian Units

In the South Asian numbering system, the lakh serves as a key intermediary unit, with 100 lakhs equaling 1 , which represents 10 million. This hierarchical structure extends to higher denominations, such as the , defined as 100 crores or 1 billion, providing a scaled framework for expressing large quantities without relying on Western million-based groupings. Nepali numbering closely mirrors the Indian system, employing the term lākh for 100,000 and integrating it with local multipliers like karoḍ for crore (10 million), though numbers beyond 10,000 are often verbalized in lakhs rather than hundreds of thousands. In contrast, Sri Lanka historically utilized lakh and crore in its traditional counting—writing, for instance, 21,440,000 as 2,14,40,000—but transitioned to the international system during metric standardization in the mid-20th century, retaining lakh primarily in informal or financial contexts tied to Indian influence. While sharing a foundation with East Asian traditions, the lakh of diverges notably from the Chinese wàn (10,000) and Japanese man (10,000), where groupings emphasize four-digit clusters up to (100 million in Chinese) or oku (100 million in Japanese), resulting in different verbal and written expressions for mid-scale numbers like , which might be articulated as 10 wàn in Chinese rather than a single unit. The lakh's conceptual roots trace to the ancient lakṣa, denoting in Vedic literature from around 1500–500 BCE, but historical divergences emerged during the Mughal era (1526–1857), when pre-Islamic units were adapted into Persianate administrative practices for revenue and trade, standardizing lakh within a more uniform hierarchy that incorporated Arabic-influenced terms for even larger scales, unlike the varied multipliers in earlier regional systems.
