Crore to Million Converter (crore, lakh ↔ million, billion)

Understanding the crore to million converter — concept and principle

This converter changes amounts between crores and lakhs and the international units million and billion. It shows the result, the amount in millions, billions, crores and lakhs, and the full number in Indian and international notation. It helps when comparing Indian company figures, budgets or salaries with international reports.

1 crore = 10 million — with the default inputs: 50 million.

How it is calculated

1 crore = 10⁷ = 10 million; 100 crore = 1 billion
crores × 10 = millions; millions ÷ 10 = crores
1 lakh = 10⁵ = 0.1 million
Plain number = value × size of the "from" unit; result = plain number ÷ size of the "to" unit
Indian notation groups digits in twos after the first three; international notation in threes

The principle

A crore is ten million exactly, so converting between crores and millions only moves the decimal point by one place. The difficulty is in the reading, not the arithmetic: Indian notation writes 5 crore as 5,00,00,000 and international notation writes the same number as 50,000,000. Writing both forms side by side removes the confusion.

Worked example

Default: 5 crore to millions.

Plain number = 5 × 10⁷ = 50,000,000.
Result = 50,000,000 ÷ 10⁶ = 50 million.
In billions 0.05; in crores 5; in lakhs 500; in millions 50.
Indian notation 5,00,00,000; international notation 50,000,000.

Each point is the calculator re-run with only “Number” changed; the gold point is the default example. Change the inputs above and this chart follows your numbers.

Number	Result
1.25	12.5 million
2.5	25 million
3.75	37.5 million
5	50 million
6.25	62.5 million
7.5	75 million
10	100 million

How to read the result

A quick rule: multiply crores by 10 for millions, divide by 100 for billions. So a project costing 1,000 crore costs 10 billion in the same currency. For Korean readers, 1 crore = 1,000만 and 100 crore = 10억.

Common mistakes

Multiplying by 100 instead of 10.
Reading Indian commas as international ones.
Converting the number but not the currency.
Confusing "lakh crore" (10¹²) with "crore".

Keep in mind: Check whether a figure in a report is already converted to another currency before comparing.
