How to use it
- Type the amount in Amount. Put the cents after a dot, for example 1234.56.
- Choose Plain words for a letter or an invoice, or Cheque style for a cheque.
- Check the Currency. It starts as the currency of this page; choose No currency to write the number alone.
- Copy the text from Amount in words, or save it with Download.
How the words are built
The whole part of the amount is split into groups of three digits, counted from the right: units, thousands, millions, billions and trillions. Each group is read in words and followed by its scale word. A group of zeros is skipped, so 1,000,000 reads as one million.
The cents are two digits. With a currency they are read as cents or pence after the currency name. Without a currency they follow the word point, digit by digit: 0.05 reads as zero point zero five.
- Thousand, million, billion and trillion follow the short scale: a billion is 10 to the power 9 and a trillion is 10 to the power 12.
- Numbers from 21 to 99 that are not round take a hyphen: twenty-one, fifty-six.
- No and is written inside a whole number, so 101 reads one hundred one. The and comes before the cents.
Cheque style
A cheque states the amount twice: in figures and in words, so that the figures cannot be changed without the words showing it. This tool writes the words with a capital letter at the start, the cents as a fraction over 100 (for example 56/100), and the currency name in the plural.
Before you sign a cheque, compare the amount in figures with the amount in words, and follow the layout your bank asks for. The bank's rules decide the final form.
What this tool does not cover
- Negative amounts, and amounts with more than two decimals.
- Currencies other than those in the list, and the names of currencies in other languages.
- The legal form of a particular cheque or invoice. Your bank or your accountant gives the binding form.
Worked example: 1,234.56 US dollars
The whole part, 1,234, reads as one thousand two hundred thirty-four. The cents, 56, read as fifty-six, and with a currency they become dollars and cents.
In cheque style the same amount is written with a capital letter and the cents as a fraction over 100: One thousand two hundred thirty-four and 56/100 dollars.
| Output | Result |
|---|---|
| Amount in figures | $1,234.56 |
| Plain words | one thousand two hundred thirty-four dollars and fifty-six cents |
| Cheque style | One thousand two hundred thirty-four and 56/100 dollars |
Frequently asked questions
Why is the amount a text box and not a number box?
A number box stores the amount as a binary number, which cannot hold every cent of very large amounts. The text box keeps every digit, so 999,999,999,999,999.99 is written out exactly, cent included.
How does the tool read a comma in the amount?
A comma followed by exactly three digits is a thousands separator, so 1,234 is one thousand two hundred thirty-four. Any other comma is the decimal mark, so 2,5 is two and a half.
Why are the cents written as 56/100 on a cheque?
The fraction over 100 states the cents as a part of the currency unit, so the amount can be checked at a glance. It is a common way to write cents on a cheque, but your bank's layout is the one to follow.
Does the tool write and before the hundreds, as in one hundred and one?
No. It follows US usage, so 101 is one hundred one. Some British writing adds and before the last two digits, and you can add it by hand where your style asks for it.
Does the amount I type leave my device?
No. The figures and the words are made in your browser. Nothing you type is sent to our server or stored by the page.
