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, romanized: lakṣa, 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]

Definition and Notation
Numerical Value
The lakh is a unit in the South Asian numbering system equivalent to exactly 100,000 (or ) in the international decimal system.[6] It serves as a fundamental grouping for expressing large quantities, representing 100 thousands.[7] In the hierarchical structure of the South Asian system, the lakh occupies a central position between smaller units like the thousand () and larger ones such as the crore ( or 10 million, equivalent to 100 lakh).[6] 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.[8] The system extends beyond the crore to accommodate even greater magnitudes, with the lakh fitting into the progression as follows:| Unit | Numerical Value | Relation to Lakh |
|---|---|---|
| Thousand | 0.01 lakh | |
| Lakh | 1 lakh | |
| Crore | 100 lakh | |
| Arab | 10,000 lakh | |
| Kharab | 1,000,000 lakh |
Written and Spoken Forms
In the Indian numbering system, 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 initial three digits (units, tens, hundreds, 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 Indian English, with a long 'a' sound akin to "lack" but elongated, while in British English it is /lak/ and in American English /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 South Asia. 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 Reserve Bank of India (RBI) officially prefers "lakh" in English-language communications, such as on cheques and reports, to standardize terminology and avoid spelling discrepancies.[9] This preference is evident in RBI guidelines and usage (as of 2024).Historical Development
Origins in Ancient Systems
The lakṣa unit, signifying 100,000, 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 ritual 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.[10][11] References to lakṣa appear in foundational Sanskrit texts, including the Rigveda 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 positional notation, relying instead on verbal multipliers for precision in liturgical and calendrical contexts. Later integrations occur in Jain literature, notably the Anuyogadvāra-sūtra (c. 300 BCE), which employs lakṣa amid expansive cosmological models, and in Buddhist scriptures like Vasubandhu’s Abhidharmakośa (c. 4th–5th century CE, drawing on earlier traditions), positioning it as the sixth decimal denomination in systematic classifications of phenomena.[10][11][12] The Brahmi numeral system (c. 3rd century 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.[13][14] In administrative treatises such as Kauṭilya's Arthaśāstra (c. 300 BCE), lakṣa-like units facilitated the accounting of revenues, with references to aggregates of 100,000 in taxation frameworks and trade regulations, illustrating its role in state fiscal mechanisms. These applications highlight how ancient numeral practices extended from ritual abstraction to pragmatic governance, laying groundwork for subsequent refinements.[10]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 South Asia, 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 Akbar and Aurangzeb detailed payments such as one lakh tolas of gold valued at 14 lakhs of rupees for provincial governance and military upkeep, embedding the term deeply into bureaucratic practices.[15] Under British colonial rule, the lakh persisted in Anglo-Indian commerce despite tensions with the imperial pound-shilling-pence system, serving as a practical tool for local transactions and record-keeping in rupees. While the East India Company and later the British Raj imposed sterling-based accounting for international trade and remittances to London, Indian merchants and regional administrations retained lakh for domestic economic activities, such as tax collections and market dealings, to bridge traditional practices with colonial oversight. This duality created conflicts, as seen in 1835 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.[16] 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 India, the Indian Coinage Act of 1955, effective from 1957, decimalized the rupee into 100 paise but retained lakh and crore in official economic reporting to accommodate South Asian conventions, as evidenced in national budgets and planning documents that expressed outlays like the First Five-Year Plan's 2,069 crore rupees (206,900 lakh rupees) in familiar units. Similar adoptions occurred in Pakistan and Bangladesh, where the inherited Indian numbering system continued in post-partition economies, with lakh used in statistical compilations for population, trade, and GDP estimates to ensure continuity from colonial-era records. The 1950s economic reforms, including the Industrial Policy Resolution of 1956, further promoted lakh in national statistics by integrating it into five-year plans' resource allocations, such as irrigation investments totaling several lakhs of rupees, to support centralized planning and public comprehension.[17][18]Modern Usage
In Finance and Commerce
In South Asia, particularly India, the lakh serves as a fundamental unit for expressing monetary values in the Indian Rupee (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 stock market, share prices are denominated per unit but imply lakh-scale impacts on market capitalization; Reliance Industries Limited achieved a historic milestone by reaching a market value of 20 lakh crore INR in 2024, underscoring the term's role in scaling corporate valuations for investors and analysts.[19] The lakh also plays a key role in commodity markets, where it denotes large quantities of precious metals like gold 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 Multi Commodity Exchange (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 kilogram, reflecting the unit's practicality for high-value trades amid global volatility.[20][21] 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. Public sector banks in India have written off loans totaling 12.08 lakh crore INR since fiscal year 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 Interest Subvention Scheme from 3 lakh to 5 lakh INR for farmers via Kisan Credit Cards, supporting over 7.7 crore beneficiaries with short-term credit. Additionally, interest-free loans to states reached 1.11 lakh crore INR by early 2025, illustrating the unit's integration into fiscal planning and disbursement mechanisms.[22][23][24] 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.[25][26]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.[27] 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.[28] This notation aligns with official publications from the Office of the Registrar General & Census Commissioner, enabling precise breakdowns without cumbersome decimal places.[29] 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.[30] 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 density, infrastructure needs, and resource allocation. In Mumbai, for instance, the Brihanmumbai Municipal Corporation (BMC) uses lakh-based figures for ward-level planning, noting the city's core districts exceed 120 lakh residents collectively, which informs water supply and transport projections. Nationally, the Ministry of Housing and Urban Affairs incorporates lakh notations in reports like the Census Town 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 public health outcomes. The Ministry of Health and Family Welfare's COVID-19 updates, disseminated via Press Information Bureau (PIB), tracked cases as low as 7.1 per lakh population in early 2020, rising to over 30 per lakh by mid-year, aiding in containment strategies.[31] Similarly, tuberculosis notifications under the National TB Elimination Programme declined from 237 to 195 cases per lakh population between 2015 and 2023, as reported in 2025 health releases.[32] In education, 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 Sanskrit word lakṣa (लक्ष), which originally signified a "sign," "mark," or "target," and later extended to denote the numerical value of 100,000, with its earliest attestation in the Rigveda referring to a "prize" in dicing contexts.[33] 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.[34] In Middle Indo-Aryan languages, lakṣa evolved into forms like lakkha in Prakrit and Pali, appearing in ancient Buddhist and Jain texts to represent both literal marks and the quantity 100,000, facilitating its transmission through vernacular literature and religious scriptures.[35] These adaptations simplified the aspirated and retroflex sounds of classical Sanskrit, embedding the term in everyday and scholarly discourse across northern and central India by the early centuries CE. During the period of Islamic rule in South Asia, particularly under the Delhi Sultanate and Mughal Empire, 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.[3] This integration occurred as Persian became the lingua franca of governance from the 13th century onward, propagating the term via court documents, trade ledgers, and multicultural exchanges.[36] Phonetically, the term underwent shifts from the Sanskrit pronunciation /ˈlək.ʂə/—featuring a retroflex sibilant and schwa vowel—to the Prakrit-Pali /ˈlək.kʰə/, and further to the modern Hindi-Urdu /lɑːkʰ/, simplifying the consonant cluster while retaining the core vowel quality; in English loanwords, it is typically rendered as /læk/ or /lɑːk/, aligning with anglicized simplifications in colonial-era texts.[3] The numerical value of 100,000 remains intrinsically tied to this linguistic lineage.Variants Across Languages and Regions
In Hindi and Urdu, the term for lakh is spelled लाख (lākh) in the Devanagari script for Hindi and لاکھ (lākh) in the Nastaliq script for Urdu, maintaining a consistent pronunciation across both languages. In Nepali, it is spelled लाख (lākh), similar to Hindi.[37] 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.[38] The Tamil equivalent is இலட்சம் (ilaṭcam), reflecting a Dravidian adaptation of the concept.[39] In Telugu, it appears as లక్ష (lakṣha), closely aligned with Sanskrit-derived forms in other Dravidian languages.[40] In Pakistan and Bangladesh, 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 Urdu (لاکھ) in Pakistan and Bengali (লাখ) in Bangladesh are used in vernacular settings.[41] Among South Asian diaspora communities, adaptations include the use of "lakh" in Fiji Hindi, as in ek lakh for one hundred thousand.[42]Comparisons with Other Numbering Systems
With International Systems
The lakh, defined as 100,000 or , stands in contrast to the international short scale numbering system predominantly used in English-speaking countries, where one million equals 1,000,000 or , corresponding to precisely 10 lakhs.[43] 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 Europe and some scientific contexts, one milliard represents , equivalent to 10,000 lakhs, as it multiplies the million () by another thousand.[44] In global finance and commerce, the lakh's use can lead to misinterpretations when data from South Asian contexts is shared internationally without conversion, potentially causing errors in economic analyses or investment decisions. For instance, reports originating from India 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 United Nations, in its socioeconomic data 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.[45]With Other South Asian Units
In the South Asian numbering system, the lakh serves as a key intermediary unit, with 100 lakhs equaling 1 crore, which represents 10 million. This hierarchical structure extends to higher denominations, such as the arab, defined as 100 crores or 1 billion, providing a scaled framework for expressing large quantities without relying on Western million-based groupings.[41][7] 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.[46][47][48] While sharing a decimal foundation with East Asian traditions, the lakh of 100,000 diverges notably from the Chinese wàn (10,000) and Japanese man (10,000), where groupings emphasize four-digit clusters up to yì (100 million in Chinese) or oku (100 million in Japanese), resulting in different verbal and written expressions for mid-scale numbers like 100,000, which might be articulated as 10 wàn in Chinese rather than a single unit.[49] The lakh's conceptual roots trace to the ancient Sanskrit lakṣa, denoting 100,000 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.[41][50]References
