— How it works
Converted value = amount × 10^(from exponent − to exponent). Each unit is a fixed power of ten: lakh = 10⁵, crore = 10⁷, million = 10⁶, billion = 10⁹, lakh crore = trillion = 10¹².
Two number systems, one bridge
The world counts large numbers two ways. The international system groups by thousands — thousand, million (a thousand thousand), billion (a thousand million), trillion. The Indian system, used across South Asia, groups by hundreds after the first thousand — thousand, lakh (a hundred thousand), crore (a hundred lakh), and on to lakh crore. Because the grouping differs, the same number has two names, and converting between them trips people up. This tool is the bridge: enter an amount in either system and read it in the other, with a reference table that lines every unit up by its power of ten.
The three anchors worth memorising: 10 lakh = 1 million · 100 crore = 1 billion · 1 lakh crore = 1 trillion. And the one everyone needs: 1 crore = 10 million.
The digit grouping is the real trap
It is not just the names — the commas sit in different places, and that is what makes a number hard to read across systems. The international convention places a comma every three digits, so ten million is written 10,000,000. The Indian convention commas the last three digits and then every two, so the same number is 1,00,00,000 — read as “one crore”. A figure like ₹15,00,00,000 (15 crore) becomes 150,000,000 (150 million) once regrouped. This converter shows the full number both ways at once, so you can see exactly where the commas move.
The reference table, by power of ten
Every unit is simply a power of ten, which is why conversion is exact and never needs live data. Thousand is 10³, lakh 10⁵, million 10⁶, crore 10⁷, billion 10⁹, and trillion (the same size as one lakh crore) 10¹². To convert, you shift by the difference in exponents: crore (10⁷) to million (10⁶) is one power of ten, so 1 crore = 10 million. The table below highlights the two units you picked and shows your amount expressed in every unit at once — a full cross-reference you can scan in a second.
— Reader questions
How many millions is one crore?
One crore equals 10 million. A crore is 10⁷ (10,000,000) and a million is 10⁶ (1,000,000), so a crore is ten times a million. Likewise 10 crore = 100 million, and 100 crore = 1 billion.
How many lakhs make a million?
Ten lakh make one million. A lakh is 100,000 (10⁵) and a million is 1,000,000 (10⁶), so it takes ten lakh to reach a million. Half a million is 5 lakh.
What is one billion in crore?
One billion equals 100 crore. A billion is 10⁹ (1,000,000,000) and a crore is 10⁷, so a billion is a hundred crore. Ten billion = 1,000 crore, and 1 lakh crore = 1 trillion.
Why is a crore written 1,00,00,000 and not 10,000,000?
They are the same number — the comma placement differs. The Indian system groups the last three digits then every two (1,00,00,000); the international system groups every three (10,000,000). The digits are identical; only the commas move.
What is a lakh crore?
A lakh crore is one lakh (100,000) multiplied by one crore (10,000,000) = 10¹² — exactly one trillion. It is the largest everyday Indian unit, equal to 1,000 billion or 100,000 crore.
