The Indian numbering system, used today in India, Pakistan, Bangladesh, Nepal and Myanmar (Burma), is based on grouping by two decimal places, rather than the three decimal places commonplace in most parts of the world. This system of measurement introduces separators into numbers in places appropriate to the two-digit grouping. For example, 30 million (3 crore) rupees would be written as Rs.3,00,00,000, with commas at the thousand, lakh, and crore levels, instead of Rs.30,000,000.

The terms crore and lakh are in widespread use today in Indian English.

The table below follows the short scale usage of billion being a thousand million. In India, following former British usage, the long scale was used, with one billion equivalent to one million million.

The higher numbers listed above arab are not commonly used, though padma and kharawb are sometimes used in Hindi. Neel, Padma, Shankh are more commonly found in old sections of Indian Mathematics.

Instead of saying the higher numbers, it is more common to use lakh and crore repeatedly or in combination, saying 1 lakh crore for 10¹² or one trillion.

The term crore (کرور [Korur] in Persian) was also used in Iran until recent decades, but with the meaning of 500,000.

In Sinhalese, a crore is called kōţiya (Sanskrit: कोटि / Koti), and a lakh is called lakshaya (Sanskrit: लक्ष / Laksha) . In Tamil a crore is called Kodi or கோடி and a lakh called laksham லக்ஷம். In Kannada a Lakh is called Laksah or ಲಕ್ಷ and a crore is called Koti or ಕೊಟಿ

Lakh has entered the Swahili language as "laki" and is in common use.
