Lakh Crore to Million Billion Converter

Lakh and crore against million and billion. The Indian system groups digits in twos above the first thousand, so the same number carries commas in different places.

Also called: crore to million, lakh to million converter.

In the Indian system

How this is calculated
Method and background

How this is calculated

A lakh is a hundred thousand and a crore is ten million, so a crore is not a round number of millions in the western scale and vice versa. The digit grouping follows the same logic: Indian grouping is 3-2-2, giving 1,00,00,000 for a crore where western grouping gives 10,000,000. Both are shown because a figure copied between the two conventions is a common source of error by a factor of ten.

the Indian system groups in twos above the first thousand, which is why the comma positions differ

Frequently asked questions

How many crore is a billion?
One hundred crore. A billion is 10^9 and a crore is 10^7, so the factor is a hundred.
Why are the commas in different places?
Indian grouping is 3-2-2 rather than 3-3-3, so after the first thousand the digits group in pairs. A crore is 1,00,00,000 in India and 10,000,000 elsewhere.
