🔡 Number to Words Converter: Write Numbers in English Words

How to use it

1. 1. Type a whole number

   Enter any whole number from 0 up to 999,999,999,999. You can add commas or spaces between the digits. Decimals and negative numbers are not supported.

2. 2. Choose the spelling style

   American style writes one hundred one. British style adds and, so it is one hundred and one, and one thousand and one. Pick the style your class or exam follows.

3. 3. Add the ordinal form if you need it

   Tick the ordinal box to turn the answer into first, second, twenty-second, one hundred first or fortieth. This is used for dates, positions and floors of a building.

4. 4. Read it out or copy it

   Press Write it in words. Read the words aloud, check a student's spelling against them, or press Copy to paste them into a worksheet, a cheque exercise or a document.

Ideas for class and home

• Checking spelling homework

  Students write number words from dictation, then type the numbers here to compare. Common slips such as fourty, ninty and eigth show up immediately and can be discussed.

• Comparing American and British English

  Switch the style on a class screen and ask which version students have seen. The "and" in a hundred and one is a good starting point for a short lesson on regional differences.

• Writing cheques and forms

  Learners of English practise amounts written in words, as on a cheque or a contract. Large amounts with several groups train the order of hundreds, thousands and millions.

• Ordinals for dates and rankings

  Use the ordinal option to practise the twenty-first of June, the thirty-second floor or the hundredth day of school, where the ending changes only on the last word.
