Large Numbers
Large numbers can be confusing because countries do not always group and name them in the same way. A value written as 10 million in an international report may be written as 1 crore in South Asian writing. A figure shown as 1 billion may also be described as 100 crore.
This page gives one clear view of the same amount across both naming systems. You can enter a full number, lakh, million, crore, billion, or trillion, and the matching values will appear together with comma formats and number words.
Before you enter a number
Use the full number field when you already have the raw digits, such as 250000000. Use lakh or crore for South Asian figures, and use million, billion, or trillion for international figures. You can also use the quick input box for phrases such as 5 crore, 12 lakh, 2.5 billion, or 750 million.
Why these formats matter
Large values appear in news, government budgets, company valuations, population data, property prices, market reports and school work. Reading the same value in both systems reduces mistakes and makes figures easier to compare.
Enter one value below to see the same amount as a full number, lakh, million, crore, billion and trillion, or type a phrase such as 5 crore or 2.5 billion.

Understanding large-number names
Number names are shortcuts for groups of zeros. One lakh is 100,000. One million is 1,000,000, which is 10 lakh. One crore is 10,000,000, which is 100 lakh or 10 million. One billion is 1,000,000,000, which is 1,000 million or 100 crore. One trillion is 1,000,000,000,000, which is 1,000 billion or 100,000 crore.
International and South Asian comma styles
The international comma style groups digits in sets of three, such as 1,000,000,000. The South Asian comma style keeps the first group of three digits and then groups the remaining digits in pairs, such as 1,00,00,00,000. Both can describe the same value, but they look very different at first glance.
Quick reference table
This table shows common large values in both systems. It is meant as a reading guide for reports, articles, budgets, valuations and study notes.
| Full number | South Asian name | International name |
|---|---|---|
| 100,000 | 1 lakh | 0.1 million |
| 1,000,000 | 10 lakh | 1 million |
| 10,000,000 | 1 crore | 10 million |
| 100,000,000 | 10 crore | 100 million |
| 1,000,000,000 | 100 crore | 1 billion |
| 1,000,000,000,000 | 100,000 crore | 1 trillion |
Useful relationships to remember
One million equals 10 lakh. One crore equals 10 million. One billion equals 100 crore. One trillion equals 100,000 crore. These four relationships cover many of the large figures seen in business, finance, population and public spending content.
Examples
If a company value is written as 500 crore, the same value is 5 billion, 5,000 million, 50,000 lakh, or 5,000,000,000 as a full number.
If a budget is written as 2.5 billion, the same value is 250 crore, 25,000 lakh, or 2,500 million. If a report says 0.75 trillion, the same value is 750 billion or 75,000 crore.
