One question is very popular that 1 billion is equal to how many crores?
1 Crore = 100 Lakh
10 Lakh = 1 Million
Therefore, 1 Crore = 10 Million
1000 Million = 1 Billion
Hence, 1 Billion = 100 Crore
If you want to convert 1 Billion USD to Indian Rupee then multiply with the current date value of the $ (USD = US Dollar). For example convert 2 Billion USD to Indian rupees if ONE USD rate is equal to 50 Rupees.
