About these units

Arab (Indian) (arab)

Indian subcontinentTraditional unit (still used in some regions)

One hundred crore (10⁹), the same as a short-scale billion. Used in the South Asian number system.

Western numbers are named in steps of a thousand, with a new word at each third power of ten: thousand, million, billion. The Indian system adds a new word at every second power instead, giving lakh for 100,000, crore for 10 million, arab for 1,000 million and kharab for 100,000 million. An arab is a hundred crore, or 10 to the ninth power.

That equals the short-scale billion, so the two words name the same quantity, which sometimes causes confusion between Indian and international usage. Digits are grouped to match: the first three from the right are one group, and then pairs follow, so an arab is written 1,00,00,00,000 rather than 1,000,000,000.

The system is official and preferred in India, Pakistan and Bangladesh, and Indian English publications use lakh and crore for rupee amounts. Nepal and Sri Lanka used it in the past but have moved to the international system, and the Maldives still uses lakh in speech. Sanskrit mathematicians such as Shridhara named large numbers beyond koti in several incompatible ways, so older texts do not always give the same value.

1 arab (Indian) = 1,000,000,000 pieces (exactly).

Lakh (lakh)

Indian subcontinentCurrent unit

One hundred thousand (10⁵). The standard unit in the Indian numbering system, written 1,00,000.

Gambling stakes may have named the lakh. The Sanskrit word lakṣa originally meant a mark, a target or a stake in gambling, and in the Classical Sanskrit of the Gupta era it became the numeral for 100,000. English borrowed it from South Asia, and other languages did too: in Malay and Indonesian, laksa means 10,000 instead. The Indian numbering system gives a name to nearly every second power of ten, which is why a hundred thousand gets its own word rather than being called ten myriads or a hundred thousands.

A lakh is 100,000, written 1,00,000 under Indian digit grouping: the first three digits from the right form one group and every later group has two digits. It is the everyday system in India, Pakistan and Bangladesh, where it is preferred over the international one. Rupee amounts are stated in lakhs, so 150,000 rupees is 1.5 lakh. Indian English also uses lakhs of as a loose phrase for very many, and formal publications usually give foreign currencies in the international system and rupees in lakhs and crores.

1 lakh = 100,000 pieces (exactly).
