About this tool
Convert any figure into its written-out English form — 1,042 becomes "one thousand forty-two" — including decimals and currency amounts. It's the tool behind error-free cheques, legal documents where amounts appear in both forms, and invoices for jurisdictions that require totals spelled out.

Enter the number to convert — an integer, a decimal, or a monetary amount of any realistic size.
- 2
The written-out form appears instantly, following standard English number-naming conventions through thousands, millions, and beyond.
- 3
Copy the words into your cheque, contract, invoice, or document exactly as generated.

Writing Amounts Correctly

Frequently asked questions
Why do cheques require the amount in words?
The written words are the legally controlling amount in most jurisdictions — banks resolve any mismatch with the numerals in favor of the words. Digits are easy to alter (a 1 becomes a 4) while words are not, which is exactly why the convention exists and why an error in the words is serious.
How are decimal amounts handled?
For currency, the standard cheque format expresses cents as a fraction — 250.75 becomes "two hundred fifty and 75/100". For plain decimals, digits after the point are read out individually. Match the format your document expects; banking and legal conventions differ from mathematical ones.
Should I write "and" in numbers like 105?
American convention omits it — "one hundred five" — reserving "and" for the decimal point in currency amounts. British convention includes it: "one hundred and five". Both are understood everywhere; for cheques in the US, following the American form avoids any ambiguity with cents.
How large a number can be converted?
Well beyond anything a document plausibly needs — millions, billions, and trillions all convert with correct scale words in place. Precision, not size, is the practical constraint: extremely long numbers should be double-checked digit by digit on entry, since a typo converts just as fluently as the right number.
