Type a whole number from 1 up.
Capital letters, hyphens, and “and” are all fine. Also understands “negative”, “minus”, and “point”.
How to use it
- Type the number or the amount. “1,234,567.89”, “1234567.89” and “$1,234.56” all work.
- Pick the currency (or “No currency”) and whether you want the cents spelled out or as a fraction, like “56/100”.
- Adjust the capitalization or turn on the British “and” if you need it. The result updates as you type.
- Copy the text with one click. The other tabs give ordinals (twenty-first) and turn words back into a number.
Frequently asked questions
How do I write the amount on a check in words?
Write the dollars in words and the cents as a fraction over 100: “One thousand two hundred thirty-four and 56/100”. Pick US dollars and, in More options, choose the template that starts with “Check”. It writes the cents as a fraction and adds the word “dollars” at the end. Banks can ask for a specific format, so check yours.
Should I write “and” in “one hundred and five”?
In American English the “and” is usually left out: “one hundred five”. British English keeps it: “one hundred and five”, “one thousand and one”. To get that style, turn on the British “and” option in More options. On a check, the “and” that comes before the cents (“and 56/100”) is always written.
How are decimals and cents read?
With a currency, the decimals become cents, rounded to two places: 12.5 is “twelve dollars and fifty cents”. Without a currency, each digit after the point is read one by one: 3.14 is “three point one four”.
How does it read commas and periods?
The comma separates thousands and the period is the decimal point, as in English: “1,234.56”. If you type the European style, “1.234,56”, we read it that way and tell you how. A lone period followed by three digits, like “1.234”, is read as a decimal, and we show a note so you can double-check.
What is the largest number I can convert?
Up to 999 octillion, just under 10^30. We use the short scale used in the US and, today, the UK: a billion is a thousand million (10^9) and a trillion is a million million (10^12).
Is my number stored anywhere?
No. The conversion happens in your browser and nothing is sent to a server. The recent conversions list stays on your device, and you can clear it with one button.
How English writes numbers out
- Hyphens: numbers from 21 to 99 that are not round take a hyphen: twenty-one, forty-five, ninety-nine.
- “And”: American style leaves it out (one hundred five); British style puts it after “hundred” and before the last group (one hundred and five, one thousand and one).
- No plural on the multiplier: two hundred, three thousand, five million, never “two hundreds”.
- Short scale: a billion is 109, a trillion is 1012, a quadrillion is 1015.
- Negative numbers start with “negative” (or “minus”): negative fifteen.
Writing a check
On a check the amount goes in numbers and again in words, so nobody can alter it easily. In the US the dollars are written in words and the cents as a fraction over 100, followed by the word “dollars” that is often already printed at the end of the line: One thousand two hundred thirty-four and 56/100. Start at the far left and draw a line through any space that is left. If the words and the numerals disagree, the words generally take precedence, so make sure they match. Your bank may have its own rules.
Examples
- 21 → twenty-one
- 101 → one hundred one (British: one hundred and one)
- 1,000,000 → one million
- 1,001 → one thousand one (British: one thousand and one)
- 1,234.50 → one thousand two hundred thirty-four dollars and fifty cents
- 0.5 → zero point five
Ordinals and words to number
The ordinals tab writes any whole number as an ordinal: first, second, third, twenty-first, one hundredth, and gives the short form too (1st, 2nd, 3rd, 21st). The words-to-number tab reads phrases like “three million five hundred thousand” or “negative twelve point five”, with or without hyphens. If you need Roman numerals instead, try the Roman numeral converter, and for fixing the capitalization of a longer text, the case converter.
