How it works
Enter a number and the tool spells it out in English words using the standard short-scale naming (thousand, million, billion, and so on), handling hundreds, tens, and the teens correctly. A reverse mode parses written words back into a numeric value. This is handy for writing amounts on cheques and legal forms where the figure must also appear in words. All conversion runs locally in your browser.
1234 → "one thousand two hundred thirty-four"
Common use cases
- Writing the amount in words on a cheque.
- Spelling out a figure for a contract or invoice.
- Converting a written amount back to digits.
Frequently asked questions
How large a number can it spell?
It handles numbers up into the trillions using short-scale names. Very large values beyond standard named scales are labeled with the highest available group name.
Does it handle decimals?
Yes. The whole-number part is spelled in words and the decimal part is read out digit by digit (or as cents-style wording where appropriate).
Is it English only?
Yes. This converter uses English short-scale number names. Other languages have different grouping and naming rules.
