What Is a Number to Words Converter?
A number to words converter writes a number in words, such as 1,234 as one thousand two hundred thirty-four, and can also read number words back into digits. Spelling numbers out matters on cheques, contracts, invoices and formal letters, where words are harder to alter than digits. It is also useful for teaching, for scripts that read numbers aloud and for checking your own writing.
This number to words converter handles whole numbers up to 36 digits, negative numbers and decimals. It works line by line, so you can convert a whole list at once.
How to Use This Number to Words Converter
- Enter one number per line, or one set of number words per line.
- Choose the direction: numbers to words, or words to numbers.
- For numbers to words, pick American or British style.
- Press Convert, then copy the result or read the line-by-line table.
Examples
| Number | In words |
|---|---|
| 7 | seven |
| 42 | forty-two |
| 101 | one hundred one (American) or one hundred and one (British) |
| -5 | minus five |
| 3.14 | three point one four |
| 1,000,000 | one million |
The tool uses the short scale, in which a billion is a thousand million. The difference from the long scale is explained in the short and long number scales on Wikipedia.
Words to Numbers
The reverse direction reads standard English number words, from zero up to the decillions. It understands hyphens, the word and, and words such as minus, negative and point. For example, two hundred and five point five becomes 205.5. If a word is not recognized, the tool names it, so you can fix the spelling.
Tips for Formal Writing
- On cheques and contracts, write the amount in words and in digits, and make sure they agree.
- Style guides often spell out numbers below ten and use digits above that. Pick one rule and keep it.
- For money, add the currency yourself, since the tool writes only the number.
- Check large values twice, because a misplaced comma changes the number a thousandfold.

Fewer Mistakes in Formal Documents
Writing long numbers in words by hand invites small errors, such as a missing hyphen or a wrong scale word. The converter applies the same rules every time. Use it to prepare cheques, invoices and legal text, then read the result once to confirm that it matches the digits you meant.
