How to convert a number to words online

  1. Type a number

    Enter any number in the field, including decimals like 12.34, negative numbers, and zero.

  2. Read the words

    The plain reading, an ordinal form, and a dollars and cents form appear straight away as you type.

  3. Match the style

    Switch between American and British reading and pick a capitalization, then copy the form you need.

Why use this tool

Three forms at once

Every number is written three ways: the plain reading, the ordinal form ending in words like fourth, and a dollars and cents form for money.

Decimals, negatives, and zero

Decimals are read digit by digit after the word point, negatives are prefixed with the word negative, and zero reads as zero rather than a blank.

American or British reading

American reading drops the word and, so 123 is one hundred twenty-three, while British reading keeps it as one hundred and twenty-three.

Case to match the document

Switch the whole result between lowercase, sentence case, title case, and full capitals to suit a cheque, an invoice, or a form.

Very large numbers

Long whole numbers up to 66 digits are named in full, in groups from thousands and millions up through the vigintillions.

About this tool

A number to words converter writes a figure out in plain English, the way you would say it aloud or spell it on a cheque. Type 1234 and you get one thousand two hundred thirty-four. It handles decimals, negative numbers, and zero, and it updates the moment you type, so there is no convert button to press. Alongside the plain reading it also gives you the ordinal form, one thousand two hundred thirty-fourth, and a dollars and cents form for writing out amounts of money.

Two small options let you match the style you need. American reading drops the word and, so 123 reads as one hundred twenty-three, while British reading keeps it as one hundred and twenty-three. A case control switches the whole result between lowercase, sentence case, title case, and full capitals, which is handy when the words go onto a cheque, an invoice, a legal document, or a form that wants one particular style. Decimals are read digit by digit after the word point, and money is rounded to the nearest cent.

It reads very large values too, naming groups from thousands up through millions, billions, trillions, and far beyond, so long numbers come out in full rather than as shorthand. Everything is worked out on your device as you type. If you also need the classic letter form, the roman numeral converter covers that, and the number base converter handles binary, hex, and other bases.

Frequently asked questions

How does it convert a number to words?
It splits the number into groups of three digits, names each group, and adds the scale word for its position, such as thousand or million. The result appears live as you type, with no convert button to press.
Does it handle decimals, negatives, and zero?
Yes. Decimals are read digit by digit after the word point, so 12.34 becomes twelve point three four. Negative numbers are prefixed with the word negative, and zero reads as zero.
What is the difference between American and British reading?
American reading drops the word and, so 123 is one hundred twenty-three. British reading inserts it, giving one hundred and twenty-three, and one thousand and five for 1005. Pick whichever the document expects.
How large a number can it convert?
Whole numbers up to 66 digits before the decimal point, named in groups from thousands and millions up through the vigintillions. Longer numbers get a plain message instead of a wrong answer.
What are the ordinal and dollars and cents forms?
The ordinal form is the ranking word, so 34 becomes thirty-fourth. The dollars and cents form writes an amount of money, so 12.34 becomes twelve dollars and thirty-four cents, rounded to the nearest cent.
