Crore to Lakh Converter (Indian number system)

Understanding the crore to lakh converter — concept and principle

This converter moves numbers between the Indian number names lakh and crore and the international ones thousand, million and billion. It shows the result, the number in lakhs, crores and millions, and the full figure in both Indian and international digit grouping. It is useful for reading Indian news, salaries, property prices and company reports.

1 crore = 100 lakh — with the default inputs: 250 lakh.

How it is calculated

1 lakh = 1,00,000 = 10⁵; 1 crore = 1,00,00,000 = 10⁷
1 crore = 100 lakh; 1 lakh = 0.01 crore
Plain number = value × size of the "from" unit; result = plain number ÷ size of the "to" unit
Indian notation: after the first three digits from the right, a comma every two digits
International notation: a comma every three digits

The principle

The Indian numbering system, also used in Pakistan, Bangladesh and Nepal, names numbers in steps that do not match the thousand–million–billion ladder. After a thousand comes a lakh (a hundred thousand), then a crore (ten million). Its written form follows the names: 2,50,00,000 reads naturally as "two crore fifty lakh". Converting is simply multiplying by powers of ten, but the different comma positions often cause misreadings.

Worked example

Default: 2.5 crore to lakh.

Plain number = 2.5 × 10⁷ = 25,000,000.
Result = 25,000,000 ÷ 10⁵ = 250 lakh.
In crores 2.5; in lakhs 250; in millions 25.
Indian notation 2,50,00,000; international notation 25,000,000.

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
0.625	62.5 lakh
1.25	125 lakh
1.88	187.5 lakh
2.5	250 lakh
3.12	312.5 lakh
3.75	375 lakh
5	500 lakh

How to read the result

Check the number of digits rather than commas: a crore has 8 digits, a lakh 6. When you see a figure in rupees in crores, multiply by 10 to get millions. When translating to Korean, 1 crore is 1,000만 and 1 lakh is 10만.

Common mistakes

Reading 2,50,00,000 as 250,000,000 by assuming three-digit groups.
Treating a lakh as a million.
Mixing "lakh crore" (10¹²) with "crore" alone.
Forgetting the currency when comparing figures.

Keep in mind: Spellings vary (lac, lakh; crore, cr). Check the source's notation before converting.
