Number to words converter
4,821 is four thousand eight hundred twenty-one — and “four thousand eight hundred and twenty-one” in British usage, where the “and” before the last group is not optional. On a cheque it is written the first way, because the American convention is what the banking form assumes.
Type digits to get words, or words to get digits. Both fields drive each other, and the number is read five ways: the cheque line, US style, British style, as an ordinal and grouped with commas.
The cheque line is the one most people arrive for. On a negotiable instrument the words are the controlling figure, not the numerals — UCC § 3-114 — and the cents go over 100 as a fraction precisely because a fraction cannot have a digit added to the front of it.

The ones people look up
| Number | US style | British style |
|---|---|---|
| 15 | fifteen | fifteen |
| 40 | forty | forty |
| 90 | ninety | ninety |
| 100 | one hundred | one hundred |
| 1,000 | one thousand | one thousand |
| 1,500 | one thousand five hundred | one thousand five hundred |
| 19.99 | nineteen point nine nine | nineteen point nine nine |
| 100.50 | one hundred point five zero | one hundred point five zero |
| 1,000,000 | one million | one million |
The two columns differ only where a group under a hundred follows something larger. 1,000 and 1,000,000 read identically in both; 1,500 does too, because five hundred is not under a hundred. The “and” appears exactly where a British speaker would pause.
Questions people actually ask
- How do you write a number in words on a cheque?
- Whole dollars in words, then the cents as a fraction over 100: $1,234.56 is “One thousand two hundred thirty-four and 56/100”. The word “and” separates dollars from cents and appears nowhere else, which is exactly why US style leaves it out of the number itself.
- Why do the words matter more than the figures on a cheque?
- Because UCC § 3-114 says that where the words and the numerals of a negotiable instrument disagree, the words control. A figure can have a digit added in front of it; a line of words with the space ruled out cannot.
- Is it “one hundred and five” or “one hundred five”?
- Both, in different places. British usage requires the “and”; US usage drops it, and the Chicago Manual of Style and the GPO Style Manual both write “one hundred five”. Neither is a mistake, but mixing them inside one document is.
- When should numbers be spelled out?
- Chicago spells out whole numbers from one through one hundred and round numbers above that. AP spells out one through nine and uses figures from 10. Both spell out any number that opens a sentence, which is why editors recast sentences rather than write “Two thousand twenty-six was the year”.
- Do you hyphenate numbers in words?
- Between the tens and units of a compound below one hundred: twenty-one, forty-five, ninety-nine. Not after hundred, thousand or million — “two hundred thirty-four” takes one hyphen, not two.
- What comes after trillion?
- Quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion — each a factor of a thousand up, on the short scale that both the US and modern Britain use. On the older long scale a billion meant a million million, which is why translations of older European texts are so often out by a factor of a thousand.
- How do you say a decimal out loud?
- Digit by digit after the point: 1.25 is “one point two five”, not “one point twenty-five”. Money is the exception, where 1.25 is “one twenty-five” or “one dollar twenty-five cents”.
