This article is about digit grouping of numbers in India. For the symbols used to write digits in India, see
Indian numerals.
The Indian Numbering System is used in India as well as in Bangladesh, Nepal, Pakistan, and Sri Lanka. It is based on the Vedic numbering system in which numbers over 9,999 are written in two-digit groups (or a mix of two- and three-digit groups) rather than the three-digit groups used in most other parts of the world. In Pakistan, this system is used in Urdu and other regional language media, but not in English-language media.
The terms lakh (100,000 – that is to say 1,00,000 in the Indian system) and crore (10,000,000 – that is to say 1,00,00,000 in the Indian system) are used in Indian English to express large numbers. For example, in India 150,000 rupees becomes 1.5 lakh rupees, written as ₹1,50,000 or INR 1,50,000, while 30,000,000 (thirty million) rupees becomes 3 crore rupees, written as ₹3,00,00,000 with commas at the thousand, lakh, and crore levels, and 1,000,000,000 (one billion) rupees (one hundred crore rupees) is written ₹1,00,00,00,000.
A simplified conversion between the Arabic and Indian numbering systems is :
1 million (1,000,000) = 10 lakh
1 billion (1,000,000,000) = 100 crores
