The Indian numbering system is used in the Indian subcontinent ( Bangladesh, India, Nepal, Maldives, Pakistan and Sri Lanka ) and in Burma. The terms lakh or lac ( 100,000 or 1, 00,000 in the Indian system ) and crore ( 10,000,000 or 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 or one arab अरब ) is written ₹ 1, 00, 00, 00,000. While there are specific terms for numbers larger than 1 crore, these are not commonly used, and most practitioners are not familiar with these. In common parlance, the thousand, lakh, crore terminology repeats for larger numbers. Thus 1,000,000,000,000 ( one trillion ) becomes 1 lakh crore, and is written as 10, 00, 00, 00, 00,000. The Indian numbering is equal to the western numbering system from ones then tens then hundreds then thousand then ten thousand. After ten thousand, the Indian and the western numbering divides into two parts. According to the Indian numbering system after ten thousand, it becomes lakh then ten lakh then crore then ten crore and so on. According to the Western numbering system, after ten thousand, it becomes hundred thousand then million then ten million then hundred million and so on. The two numbering system says that 10,000 ( Indian system ) = 10,000 ( Western system ). Contents 1 Use of separators 2 Names of numbers 3 Vedic numbering systems 4 Usage in different languages 5 References Use of separators The Indian numbering system uses separators differently from the international norm. Instead of grouping digits by threes as in the international system, It groups the rightmost three digits together ( till the hundreds place ) and thereafter groups by sets of two digits. One trillion would thus be written as 10, 00, 00, 00, 00,000 or one lakh crore ( or 10 kharab ). This makes the number convenient to read using thousand, lakh, crore terminology.

In India, Bangladesh and Pakistan, following former British usage, the long scale was used, with one billion equivalent to one million million.
