Lakh, Crore vs Million, Billion: Indian & International Number Systems

Guides · Money Utilities · Updated 2026

In India, we talk in lakhs and crores; the rest of the world uses millions and billions. The difference isn't just words — the grouping of digits changes, and one slip can make a crore look like a million. Whether you're reading a foreign news article, filling an international form, or comparing startup valuations, knowing the exact conversions saves you from costly mistakes. This guide explains both systems, gives you a clear conversion table, and points out the most common errors people make when switching between the two.

Why the Two Systems Coexist

The Indian numbering system groups digits in twos after the thousands place (ones, tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, crores...). The international system groups in threes (ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions...). So 1,00,000 (Indian) = 100,000 (International). And 10,00,000 = 1 million. The crore (1,00,00,000) = 10 million. This mismatch causes endless confusion: a ₹100 crore company is a ₹1 billion company internationally. A 10 million dollar fund is about ₹82 crore. Missing a zero changes the magnitude entirely.

• 1 lakh = 1,00,000 = 100 thousand = 0.1 million.
• 1 crore = 1,00,00,000 = 10 million = 0.01 billion.
• 1 million = 10 lakh; 1 billion = 100 crore; 1 trillion = 1 lakh crore.

Step-by-step: Convert Between Systems Instantly

1. Open the Lakh to Million Converter tool.
2. Enter a number in any format — say 250 lakh or 15 crore — and select the input unit.
3. The tool instantly converts it to the equivalent in millions, billions, thousands, and crores. It shows the digit grouping in both Indian and international styles.
4. It also handles decimal inputs like 2.5 lakh to show 0.25 million — no mental math required.

Conversion Table at a Glance

Common mistake: 50 lakh is 5 million, not 0.5 million. A 500 crore budget is 5 billion, not 50 billion. Use the Net Worth Calculator to track your own wealth across both scales if you hold assets internationally.

Frequently Asked Questions

Is 1 lakh equal to 100,000 or 1,00,000?

Both represent the same value — the comma placement is different. Indian system writes 1,00,000; international writes 100,000. The number is one hundred thousand.

Why do Indian TV channels use lakh and crore for global news?

It's a convention to keep numbers relatable. A "5 billion dollar deal" becomes "₹41,000 crore" — same value, more familiar to Indian audiences.

How do I read 1,234,567 in Indian system?

1,234,567 = 12,34,567 = twelve lakh thirty‑four thousand five hundred sixty‑seven. The tool shows both formats.

Is the Indian system used anywhere else?

Yes, Bangladesh, Pakistan, Nepal, and Sri Lanka also use lakh/crore. Myanmar uses a similar system with slightly different units.

Is it free and private?

Yes — the tool runs entirely in your browser, free, with no sign‑up and nothing uploaded to a server.
