What this calculator does
India, Pakistan, Bangladesh and several other South Asian countries group large numbers differently to the Western million/billion system. Instead of grouping every three digits, the Indian system groups the first three digits and then every two digits after that, which is why numbers are written as 1,00,000 rather than 100,000. A lakh is 100,000 and a crore is 10,000,000 (10 million), and both appear constantly in Indian news, property listings, salary figures and government budgets.
This crore calculator converts a value in lakh or crore into its million or billion equivalent, and back again, so a figure quoted one way can be checked against the other without doing the arithmetic by hand. The conversion factors themselves are fixed, published numbering conventions, not something that changes over time, so the same ratios apply however the value is used.
The formula
Multiply the entered value by the size of the starting unit to get an absolute number, then divide that absolute number by the size of the target unit. A lakh is 100,000, a crore is 10,000,000, a million is 1,000,000 and a billion is 1,000,000,000, so every conversion between them is just that absolute figure moved between two fixed scales.
| Term | Meaning |
|---|---|
| Lakh | One hundred thousand (100,000), written 1,00,000 in the Indian digit-grouping style. |
| Crore | Ten million (10,000,000), equal to 100 lakh, written 1,00,00,000 in the Indian style. |
| Million | One thousand thousand (1,000,000), equal to 10 lakh or one-tenth of a crore. |
| Billion | One thousand million (1,000,000,000), equal to 100 crore in this converter, using the short-scale billion common in India, the US and the UK today. |
The inputs explained
| Field | What to enter |
|---|---|
| Value | The number to convert, in whichever unit is selected under "Convert from". |
| Convert from | The unit the value above is currently expressed in. |
| Convert to | The unit to convert that value into. |
When to use it
Reading Indian property or budget figures
Indian real estate listings, company turnover figures and government budgets are usually quoted in lakh or crore. Converting to million or billion makes them directly comparable to figures reported elsewhere in the world.
Converting a Western figure into Indian units
A revenue or valuation figure quoted in millions or billions converts the other way just as easily, useful when preparing Indian-market materials that follow local numbering conventions.
Checking a converted figure by hand
Because a crore is exactly 10 million and a lakh is exactly one-tenth of a million, a rough mental check is straightforward: this calculator confirms the precise figure once the scale of the number gets large.
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How many million is a given number of crore?
A range of crore values converted to their million equivalent.
| Crore | Million |
|---|---|
| 1 | 10.000 Million |
| 5 | 50.000 Million |
| 10 | 100.000 Million |
| 25 | 250.000 Million |
| 50 | 500.000 Million |
| 100 | 1,000.00 Million |
How many lakh is a given number of million?
A range of million values converted to their lakh equivalent.
Questions
How many lakh are in a crore?
One hundred. A crore is 100 lakh, or 10,000,000 in the Western system, since a lakh is 100,000.
Is a billion the same as 100 crore everywhere?
This calculator uses the short-scale billion (1,000 million), which is standard in India, the US, the UK and most of the world today. Some older usage, mainly historical British English, used a long-scale billion equal to a million million, but that usage is now rare.
Why does India group digits differently, such as 1,00,00,000 instead of 10,000,000?
The Indian numbering system groups the last three digits together and then every two digits after that, rather than every three digits throughout. Both figures represent the same value; only the placement of the commas differs.
Is the lakh/crore to million/billion ratio ever going to change?
No. These are fixed definitions within each numbering system, not measured quantities or market rates, so the conversion factors stay the same indefinitely.
For converting between the Western million and billion scales directly, see the million to billion converter and the billion to trillion converter.
