Frequently asked questions
Why write a number in words?
Cheques, contracts, and legal documents require the amount in words as well as figures, because words are harder to alter and remove ambiguity. This converter produces that wording instantly.
Does it handle decimals and currency?
Plain number mode reads fractional digits individually. Currency mode accepts at most two decimal places and writes dollars and cents; it asks you to round inputs with more decimal places.
How large a number can it convert?
The integer part can contain up to 21 digits, through quintillions. Larger numbers are rejected rather than silently losing their scale names.
Is anything uploaded?
No. The conversion runs entirely in your browser, with no signup and nothing sent to a server.
