Number to Words Converter

Type a number and read it back in words. Words mode handles whole numbers up to decillions and reads the decimal part digit by digit, so 1234.5 becomes "one thousand two hundred thirty-four point five". US dollars mode rounds to the nearest cent and writes it check-style, like "One thousand two hundred thirty-four dollars and fifty-six cents". Negative numbers and thousands separators in your input are both fine. Everything runs in your browser.

Number

One thousand two hundred thirty-four point five six

Words mode reads the decimal part digit by digit after "point". US dollars mode rounds to the nearest cent and writes it the way you'd fill in a check.

What this tool does

It turns a number into its English spelling. Words mode gives the plain cardinal reading - the way you'd say the number out loud. US dollars mode gives the wording you'd write on a check, with whole dollars and two-digit cents spelled out and joined by "and".

How decimals are read

In words mode the part after the decimal point is read one digit at a time, so 3.14 is "three point one four" rather than "three point fourteen". That matches how people actually say decimals. Trailing zeros are dropped, so 3.50 reads as "three point five".

Writing dollar amounts

US dollars mode rounds to the nearest cent and uses the singular when the amount is exactly one (one dollar, one cent). It's handy for filling in checks, invoices, and contracts where the amount has to appear in words as well as figures.
