Where the commas go
- Start from the right and mark off the last three digits — 000. That is the thousands group, and it is the only group of three the Indian format uses.
- Working leftwards from there, place a comma every two digits. Each one marks the next unit up — lakh, then crore, then arab — which is why the groups are pairs rather than triples. For 100000000 that means 3 commas in total, giving 10,00,00,000.
- The international format instead keeps three-digit groups the whole way up, giving 100,000,000. Same number, different punctuation.

Frequently asked questions
How is 100000000 written in the Indian number format?
10,00,00,000. The first comma sits three digits from the right, then one every two digits after that, which is what produces the 2-2-3 pattern instead of the international 3-3-3.
What is the difference between 10,00,00,000 and 100,000,000?
Nothing — they are the same number. 10,00,00,000 uses Indian grouping and reads Ten Crore; 100,000,000 uses international grouping and reads One Hundred Million. Only the comma positions and unit names differ.
Why does the Indian system group digits in twos?
Because its units advance every two digits after a thousand — lakh (10⁵), crore (10⁷), arab (10⁹), kharab (10¹¹). The commas mirror the units, so each group lines up with a name you can say out loud.
What is 100000000 in Hindi and Urdu?
In Hindi, दस करोड़. In Urdu, دس کروڑ. Both use the Indian grouping shown above.
