A lakh or lac (English pronunciation: /ˈlæk/ lak or /ˈlɑːk/ lahk) is a unit in the Indian numbering system equal to one hundred thousand (100,000; 105). It is widely used both in official and other contexts in Bangladesh, India, Maldives, Nepal, Sri Lanka, Myanmar and Pakistan, and is often used in Indian English.
In English the word is used both as an attributive and non-attributive noun, and with either a marked ("-s") or unmarked plural: "1 lakh people" or "1 lakh of people", "5 lakh rupees", "5 lakh of rupees", "10 lakhs rupees", "5 lakhs of rupees" are all to be found.
The Indian numbering system also uses separators differently from the Western system — besides the three least significant digits, a comma divides every two rather than every three digits, thus:
This accords with the Indian numbering system, which has units for thousand, hundred thousand, ten million, etc.
Etymology and regional variants
The root of the word lakh is Pali lakkha— masculine mark, target, stake in gambling; from the latter derived the numerical meaning, "one hundred thousand".
