How this converter works
The tool splits your input into two parts: the integer part (before the decimal) and the fractional part (after the decimal). The integer part is converted into words using either the international or Indian scale. The fractional part is turned into either “point six seven” (plain) or “and 67/100” (cheque style).
Why two numbering systems?
- International: 1,234,567,890 → one billion two hundred thirty-four million five hundred sixty-seven thousand eight hundred ninety
- Indian: 1,23,45,678 → one crore twenty-three lakh forty-five thousand six hundred seventy-eight
Limits
This page is optimised for human-size numbers: up to quadrillions (international) and up to thousands of crores (Indian). For very large scientific values, a dedicated scientific formatter is better.
