Frequently asked questions

Quick answers about this tool.

What is the difference between Lakh/Crore and Million/Billion?

They are two ways of grouping the same digits. In the International system, groups of three digits give Thousand, Million and Billion. In the South Asian system, after the first three digits the groups are of two: Thousand, Lakh (100,000), Crore (10,000,000), Arab and Kharab. So 10,000,000 is “Ten Million” internationally and “One Crore” in South Asia.

What is the largest number it supports?

Up to 999,999,999,999 — just under one trillion (or one Kharab in the South Asian system).

How are decimals written?

The whole-number part is written normally, then the word “point” followed by each decimal digit spoken one at a time — for example, 250.75 becomes “Two Hundred Fifty point Seven Five”.

Can I use it for writing a cheque?

Yes — writing the amount in words is exactly what this is for. Just double-check your bank’s preferred format (some banks also add “only” at the end).

Is my data private?

Completely. The conversion runs entirely in your browser — nothing is uploaded, stored, or shared.
