The Indian Number System — Lakh, Crore and How to Read Any Big Number
Why ₹1,60,000 is “one lakh sixty thousand” and not “one hundred sixty thousand” — the complete guide to reading Indian numbers, with every conversion in one place.
The same six numbers, three ways
If you can read these, you can read any Indian figure. The pattern never changes — only how many pairs sit in front of the last three digits.
Three digits, then pairs
This single rule is the entire difference between the two systems. Everything else follows from it.
The first comma sits after the last three digits. Every comma after that sits after two. So the groups read 1 · 60 · 000, and the leading group names the largest scale — lakh.
Every comma sits after three digits, all the way up. The groups read 160 · 000. Identical value, different punctuation, different name — which is exactly why the two get mixed up.
The same rule scales. ₹16000000 becomes 1,60,00,000 in India — one crore sixty lakh — and 16,000,000 internationally, sixteen million. Neither is more correct; Indian banking, tax and accounting forms simply expect the Indian one, and writing a cheque the international way is a common reason forms get returned.

Lakh and crore, in millions and billions
The table people actually come looking for: what a crore is in millions, what a billion is in crore, and every step between.
| Indian | Indian digits | International digits | International |
|---|---|---|---|
| 1 Thousand | 1,000 | 1,000 | One Thousand |
| 1 Lakh | 1,00,000 | 100,000 | One Hundred Thousand |
| 10 Lakh | 10,00,000 | 1,000,000 | One Million |
| 1 Crore | 1,00,00,000 | 10,000,000 | Ten Million |
| 10 Crore | 10,00,00,000 | 100,000,000 | One Hundred Million |
| 100 Crore (1 Arab) | 1,00,00,00,000 | 1,000,000,000 | One Billion |
| 1 Lakh Crore | 10,00,00,00,00,000 | 1,000,000,000,000 | One Trillion |
The two conversions worth memorising: 1 crore = 10 million, and 1 billion = 100 crore. Everything else is a shift of the decimal point from there.
How many zeros?
Where you meet these numbers
Lakh and crore are not academic. They are the default unit for almost every large rupee figure an Indian adult encounters.
Quoted in lakh per annum — “12 LPA” means ₹12,00,000 a year.
Listed in lakh and crore — a “2.5 cr” flat is ₹2,50,00,000.
Reported in crore and lakh crore — ₹1 lakh crore is one trillion rupees.
Indian media uses crore; the same company abroad is quoted in billions.
IPL contracts and film collections are always in crore.
Cheques, GST invoices and ITR forms all expect the Indian reading.
Arab, kharab and the older ladder
The Indian system does continue past crore with its own names. In modern usage almost nobody does.
| Name | Power | Written as |
|---|---|---|
| Lakh | 10⁵ | 1,00,000 |
| Crore | 10⁷ | 1,00,00,000 |
| Arab | 10⁹ | 1,00,00,00,000 |
| Kharab | 10¹¹ | 1,00,00,00,00,000 |
| Neel | 10¹³ | 1,00,00,00,00,00,000 |
| Padma | 10¹⁵ | 1,00,00,00,00,00,00,000 |
| Shankh | 10¹⁷ | 1,00,00,00,00,00,00,00,000 |
Read the Union Budget, a bank's annual report or any business newspaper and you will find crore doing all the work, with multipliers stacked on top: 100 crore, 1,000 crore, 1 lakh crore. The arab–kharab–neel ladder survives in traditional, religious and some legal registers, and in Hindi and Nepali speech, but a figure written as “₹2 kharab” in a financial document would read as an affectation. Our converter defaults to the modern reading and keeps the Vedic names one toggle away.
Lakh or lac, crore or crores
Lakh is the standard modern spelling — it is what the Reserve Bank of India uses, and what appears on government forms. Lac is an older transliteration that still turns up in legal drafting and older contracts. Both mean 1,00,000; if you have a choice, write lakh.
Neither word takes a plural s after a number. Write ₹500 crore and ₹5 lakh — not “crores” or “lakhs”. The plural is fine when the word stands alone (“he made lakhs from it”), but after a figure, formal and financial writing keeps it singular. The same goes for the shorthand: 12 LPA means twelve lakh per annum, or ₹12,00,000 a year.
One more convention worth knowing: on a cheque or any legal instrument, the amount in words is what counts. If the figures and the words disagree, Indian banks pay the words. That is why the words line ends in “Only” with a line struck through the remaining space — and why it is worth getting right. We wrote a short guide to writing the amount in words on a cheque that covers the exact format banks accept.
Frequently asked
How many zeros are in 1 crore?
One crore has seven zeros — 1,00,00,000. That is ten million in the international system. A lakh has five zeros (1,00,000), which is one hundred thousand.
1 crore is equal to how many millions?
One crore equals ten million. The conversion runs both ways: divide crore by 10 to get million, multiply million by 10 to get crore. So 5 crore is 50 million, and 250 million is 25 crore.
How many lakhs make a million?
Ten lakh make one million. One lakh is 1,00,000 and one million is 10,00,000 — so a million is simply ten lakh written the international way.
How much is 1 billion in crore?
One billion is one hundred crore, or 1,00,00,00,000. In the older Vedic naming that same figure is one arab. A trillion is one lakh crore.
Why does India use lakh and crore instead of million?
The Indian system is far older than the international one and groups digits in pairs above the hundreds place, following the Sanskrit numeral tradition recorded in texts going back more than two thousand years. It stayed in everyday use through independence and is written into Indian banking, tax and legal convention, so government forms, bank statements and newspapers all still use it.
Is it spelled lakh or lac?
Lakh is the standard modern spelling and the one used by the Reserve Bank of India and on government forms. Lac is an older transliteration that still appears in legal drafting and some regional usage. Both mean 1,00,000 — but write lakh if you have the choice.
Is crore ever written as crores?
In careful Indian English, crore takes no plural s after a number: write “₹500 crore”, not “₹500 crores”. The same holds for lakh — “₹5 lakh”. The plural does appear in casual writing, but formal and financial documents keep it singular.
What comes after crore?
In modern usage you stay in crore and stack multipliers: 100 crore, 1,000 crore, 1 lakh crore (which is one trillion). The older Vedic ladder continues with arab (10⁹), kharab (10¹¹), neel (10¹³), padma (10¹⁵) and shankh (10¹⁷). Newspapers and the Union Budget use the modern form.
Where do the commas go in Indian numbers?
Place the first comma after the last three digits, then every two digits going left. So 160000 becomes 1,60,000 and 16000000 becomes 1,60,00,000. The international system uses threes throughout, which is why the same figure looks different in each.
What does 12 LPA mean?
LPA is “lakh per annum” — a salary of 12 LPA is ₹12,00,000 a year, or ₹1,00,000 a month before deductions. Job listings across India use this shorthand, and property listings use the same logic with “L” for lakh and “cr” for crore.
