Billion vs Crore — Which Is Bigger?
1 billion is bigger — it equals 100 crore. Written out, 1 billion is 1,000,000,000 and 1 crore is 1,00,00,000. Going the other way, 1 crore is 0.01 billion.
Side by side
| 1 Billion, Indian digits | 1,00,00,00,000 |
| 1 Billion, international digits | 1,000,000,000 |
| 1 Billion as a power of ten | 10⁹ |
| 1 Billion on the other scale | 1 Arab |
| 1 Crore, Indian digits | 1,00,00,000 |
| 1 Crore, international digits | 10,000,000 |
| 1 Crore as a power of ten | 10⁷ |
| 1 Crore on the other scale | 10 Million |
Both directions
To go from billion to crore, multiply by 100. So 5 billion is 500 crore, and 100 billion is 10,000 crore.
To go the other way, divide by 100. 500 crore is 5 billion, and 1 crore is 0.01 billion.
Where each one is used
Billion is the international unit for company valuations, national budgets and populations. Because 1 billion is exactly 1 arab and exactly 100 crore, it is also the cleanest bridge between the two systems.
Crore is the unit Indian public life runs on — film budgets and box office, cricket auction fees, company results, government schemes. Indian English almost never leaves it, preferring "1,20,000 crore" to switching up to a larger unit.

Frequently asked questions
Which is bigger, billion or crore?
Billion. One billion equals 100 crore, so it is 100 times the size.
How many crores are in 1 billion?
100. In digits, 1 billion is 1,000,000,000 and 1 crore is 1,00,00,000.
Why do the two systems have different units at all?
The international system introduces a new name every three digits — thousand, million, billion, trillion. The Indian system introduces one every two digits after a thousand — lakh, crore, arab, kharab. Both count the same way; they just group and name the digits differently, which is also why Indian commas fall at 1,00,00,000 rather than 10,000,000.
Is 1,00,00,00,000 the same as 1,000,000,000?
Yes — those are the same number written with Indian and international commas. Only the punctuation changes; the digits and the value do not.
