How do I convert a number to lakh and crore?

Type the number into the box labelled Enter an amount. The tool shows it with Indian grouping and in every scale: thousand, lakh, crore, arab, million, billion and trillion, each with a copy option.

How do I write an amount in words for a cheque?

Turn on the Rupee phrasing option under In words (Indian system). It spells the number in Indian-English words in the form Rupees ... Only, and Copy words puts the text on your clipboard.

What is the difference between lakh and million?

One lakh is 100,000 and one crore is 10,000,000, grouped 3:2:2 as in 1,23,456. A million is 1,000,000, so one crore equals ten million. The cheat sheet on the page lists these equivalents.

Why does it say my number is too large to spell out?

The words are exact only up to Shankh, which is 19 digits. Beyond that the tool shows the too-large message. Scale values above exact floating-point range are rounded, though the words stay exact.

Can I type commas or decimals in the number?

Yes. Digits, optional commas and one decimal point are accepted. Anything else triggers the message asking for a valid number. The calculation runs in your browser, so nothing is uploaded.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install.

How It Works

The Indian numbering system (thousand, lakh, crore, arab) groups digits 3:2:2 (1,23,456) while the international system (million, billion, trillion) groups in threes. This tool converts any number between the two and spells it out in Indian-English words, with optional rupee phrasing for cheques.

Type any number
It is instantly shown with correct Indian grouping (via Intl en-IN) and in every scale: lakh, crore, arab, million, billion and trillion.

An in-house Indian-scale algorithm (using BigInt so very large values stay exact) spells the number — e.g. “One Lakh Fifty Thousand” — with an optional “Rupees … Only” format for writing cheques.
