How Many Crores Are in a Billion?
There are 100 crores in 1 billion. 1 billion is 1,000,000,000 and 1 crore is 1,00,00,000, so dividing one by the other leaves 100. Going back the other way, 1 crore is 0.01 billion.
The working
1 billion is 1,000,000,000 — 10⁹. 1 crore is 1,00,00,000 — 10⁷. Subtracting the exponents gives 10², which is 100.
So to turn billions into crores, multiply by 100: 7 billion is 700 crore. To turn crores back into billions, divide by the same 100.
A useful sanity check when the numbers get large: count the zeros. Billion carries 9 and Crore carries 7, and the difference — 2 — is exactly the number of zeros in the answer.
