In words
Range and rules
- Whole numbers from 0 to 999,999,999,999 (just under one trillion) can be written out. Negative numbers are not supported.
- Amounts can have up to two decimal places, written as cents, pence, centimes, kopecks, satang and so on. The tool never rounds: three or more decimal places give an error. Won, yen and dong amounts are whole numbers, and number styles take whole numbers only.
- You can type 1,234.56, 1.234,56, 1 234,56 or 1'234.56. The last dot or comma counts as the decimal mark when one or two digits follow it; otherwise dots, commas, apostrophes and spaces separate groups of digits. Check the amount shown under the box.
- Everything is calculated in your browser. The amounts you enter are not sent to LeedyBox or saved.
Wrong wording? If a result breaks a rule of your language or of a form you have to fill in, please email us so we can fix it. Tell us the amount, the language and options you chose, the text you expected and, if you can, where the rule is written.

How to use
- Type the amount as you would write it in figures, for example 1,234.56. The line under the box shows how the tool read it.
- The page language is selected first. Pick another language if the document is in another language, and for English, Spanish, Portuguese and German pick the country, since dollars and pounds, euros and pesos, or Brazil and Portugal are written differently.
- Choose the options your form expects, such as the British "and" or "only" at the end.
- Copy the style you need: the check format puts cents as a fraction (and 56/100), the amount in words spells out dollars and cents, and the number style writes the number alone.
- Compare the words with the figures on the document before you sign it.
Frequently asked questions
How do I write cents on a check?
On a US check, write the dollars in words and the cents as a fraction of 100: $1,234.56 is "One thousand two hundred thirty-four and 56/100", followed by the printed word Dollars. Whole amounts take 00/100. "And" appears only once, before the cents, which is why US checks do not say "one hundred and five".
Should I write "one hundred and five" or "one hundred five"?
Both are English. "Hundred and" is the norm in British writing; American writing leaves the "and" out more often, and US checks leave it out because "and" introduces the cents. Turn on the British "and" option for UK documents.
Why are twenty-one to ninety-nine hyphenated?
Style guides such as the U.S. Government Publishing Office Style Manual hyphenate compound numbers from twenty-one to ninety-nine. Larger parts are separate words: one thousand two hundred thirty-four.
What happens with 1,234.567 or other extra decimals?
The tool shows an error instead of rounding, because a written amount must match the figures exactly. Round the amount the way your contract or invoice requires, then enter it again.
Can it write billions or trillions?
It writes everything up to 999,999,999,999.99, which covers billions in English. Trillions are left out because the scale words differ between languages: a Spanish billón or a German Billion is a million million, not a thousand million.
Which amount wins if the words and figures differ?
Banks generally go by the amount in words, which is why it is written out at all. Write both carefully and check that they match before you hand the document over.
Is the amount I type sent anywhere?
No. The conversion runs in your browser and the page does not save what you type. Only the rules for the language you pick are downloaded, the first time you pick it.
