Why the two systems drift apart

International grouping runs in threes all the way up, so every scale word is a thousand times the one before: thousand, million, billion. The Indian system groups the first three digits and then in pairs, so after thousand each step is only a hundred times the last: thousand, lakh, crore. That single difference is why a million is ten lakh rather than one of anything, and why the digits are written 15,00,000 in one place and 1,500,000 in the other.

Above a crore, Indian English keeps counting in crore rather than reaching for the older words: a national budget figure is written as two lakh crore, not two kharab. Those higher words exist but are archaic enough that using them would confuse rather than clarify, so this page does not.

How the Lakh Crore Converter works

The confusion is structural rather than arithmetic. International grouping runs in threes all the way up, so each scale word is a thousand times the last. The Indian system groups the first three digits and then in pairs, so after thousand each step is only a hundred times the last — which is why a million is ten lakh rather than one of anything.

Frequently asked questions

How many lakh is a million?

Ten. A lakh is one hundred thousand and a million is one thousand thousand, so a million is ten lakh. Written out, 10,00,000 in Indian grouping is exactly 1,000,000 in international grouping — the same number, with the commas in different places, which is most of why the two look so unrelated at a glance.

How many crore is a billion?

One hundred. A crore is ten million, so a billion is a hundred crore. Ten billion is a thousand crore, and a trillion is one lakh crore — which is how Indian budget figures are usually quoted, because Indian English keeps counting in crore rather than moving to a larger word.

What comes after crore?

In practice, more crore. The older words arab, kharab, neel and padma exist, but they are archaic enough in modern usage that a figure written in them would confuse most readers. Indian newspapers and budget documents write two lakh crore rather than two kharab, and that is the convention this page follows.

Why is 1500000 written as 15,00,000 in India?

Because the Indian system places a separator after the first three digits and then after every two, rather than after every three. The last three digits are grouped as hundreds, and everything above them counts in pairs — which is exactly the same structure as the words, where thousand is followed by lakh and crore at hundred-fold steps rather than thousand-fold ones.

Which countries use lakh and crore?

India, Pakistan, Bangladesh, Nepal, Sri Lanka and Myanmar, along with their diasporas and any business dealing with them. They are standard in official documents, newspapers and financial reporting across South Asia, so an international company operating there will meet both systems in the same week and often in the same spreadsheet.
