Lakh and crore converter
Convert between lakh, crore and the familiar thousands and millions.
Fill in the fields and the result will appear here automatically.
The South Asian system does not count in threes: after the thousand comes the lakh, a hundred thousand, and after that the crore, ten million. So two crore is not two million but twenty, and 1,00,00,000 groups its digits differently from the familiar 10,000,000. The converter works both ways and shows the quantity in units, in lakh and in crore at once, so the order of magnitude is visible whole.
How it works
Formula and logic
Each scale is a multiplier over the unit: thousand 10³, lakh 10⁵, million 10⁶, crore 10⁷, billion 10⁹. The value must be positive; zero and negative numbers are rejected. Result = value × source multiplier / target multiplier. Here billion means 10⁹, with no automatic long-scale interpretation. A secondary row may exceed the numeric range even when the main result is finite; it is marked separately.
Example
25 lakh is 2.5 million, that is 2,500,000.

FAQ
How much is one crore?
Ten million. The crore follows the lakh, which is a hundred thousand, so one crore holds exactly a hundred lakh.
Why are the digits grouped differently?
Because after the first group of three the digits go in pairs: 1,00,00,000 is one crore. Western notation groups everything in threes.
Where are these names used?
This calculator defines lakh as 100,000 and crore as 10,000,000. Check the unit beside the original number: names and digit grouping do not change its value.
Why does one unit in lakh show an exponent?
One unit is 0.00001 lakh, and the platform switches to exponent notation below 10⁻⁴ so that the value does not round away to zero.
