Number to Words Converter

Type or paste the number into the left panel. The words appear instantly on the right, ready to copy. For example, 2025 becomes two thousand twenty-five and 0.75 becomes zero point seven five. Commas used as thousands separators are handled automatically, so 1,000,000 reads as one million.

Yes. Click the swap button to switch direction, then type or paste the written words on the left, such as three hundred forty-two, and the digits appear on the right. The reverse direction works with whole-number words. It reads both hyphenated forms like twenty-one and spaced forms, and tolerates the word "and" as in one hundred and one.

Words that are not part of a number are left untouched, so you can paste a full line such as "a fee of two thousand five hundred dollars" and only the number words change.

It spells out numbers up through the decillions (10 to the power of 33) using American English short-scale names such as thousand, million, billion, and on up through quintillion, sextillion, and decillion. Anything larger is left as digits. If the whole input is one oversized number, a short notice explains why; inside a longer piece of text the number is simply passed through unchanged. Decimals are read digit by digit after the word "point", so 3.14 becomes three point one four.

Large values stay exact. The conversion reads the digits themselves rather than a floating-point value, so a figure like 9,007,199,254,740,993 is spelled out in full instead of being rounded.

On a US check, the amount line takes the dollars in words followed by the cents as a fraction over 100. Set Format to "Check amount" and the converter writes the line for you: 1254.30 becomes one thousand two hundred fifty-four and 30/100, and a whole-dollar figure gets "and 00/100". Set Capitalization to "Sentence case" for the leading capital the line usually carries. Some banks prefer "and no/100" for whole dollars, which you can type over the 00/100 if yours does.

Banks generally treat the written amount as the authoritative one if it disagrees with the digits in the box, which is why the wording is worth checking. Fill the line to the end, or draw a line through the leftover space, so nothing can be added after it.

Both are read as the same number. American English usually drops the "and" between the hundreds and the remainder, so 105 is one hundred five. British English usually keeps it, giving one hundred and five. The converter uses the American form by default and switches to the British one when you tick "Use 'and'", which also joins a final small group, so 1005 reads as one thousand and five. Either form is accepted when reading words back into digits.

In American usage the "and" is also what marks the decimal point in speech, as in "five dollars and fifty cents", which is where the convention comes from.

Hyphens go between the tens and the units in the compound numbers from twenty-one to ninety-nine, and only there. So 21 is twenty-one and 76 is seventy-six, but 300 is three hundred with no hyphen and 1,500 is one thousand five hundred. A larger number keeps the same rule inside each group, so 3,482 is three thousand four hundred eighty-two and 1,921 is one thousand nine hundred twenty-one.

Scale words stay singular in this form: it is two hundred and five thousand, not two hundreds or five thousands. The plural only appears when the amount is vague, as in "thousands of entries".

It depends on the style guide. AP style spells out one through nine and uses figures from 10 up. Chicago style spells out zero through one hundred, along with round numbers such as two hundred or three thousand. APA and MLA generally use figures for 10 and above and words below that, with exceptions for measurements and statistics.

Most guides agree on two points regardless: start a sentence with a word rather than a figure, and keep a series consistent, so write "3 of the 15 entries" rather than mixing a word and a figure in the same comparison.

No. The converter works with cardinal numbers, the counting forms, so 3 becomes three rather than third. Ordinals are formed from those words by changing the ending: one becomes first, two becomes second, three becomes third, five becomes fifth, twelve becomes twelfth, and most others simply take "th", as in seven to seventh. In a compound, only the last word changes, so 42nd is forty-second and 100th is one hundredth.

Years are usually read in pairs rather than as a single figure, so 1984 is said as nineteen eighty-four rather than one thousand nine hundred eighty-four. This tool gives the full cardinal form, which is the form contracts and other formal documents use. For the spoken version, convert the two halves separately: 19 and 84.

Years from 2000 onward are commonly read as whole numbers anyway, so 2025 as two thousand twenty-five matches both the written and the spoken form.

A decimal is read as "point" followed by each digit in turn, so 12.05 becomes twelve point zero five. That matches how decimals are normally spoken and avoids any ambiguity about place value. For an amount of money, switch Format to Currency, which reads the decimal as minor units instead: 12.05 becomes twelve dollars and five cents.

Symbols such as %, $, and / are left in place and the numbers around them are spelled out, so "50% of 3/4" becomes "fifty% of three/four", which you can then tidy up into "fifty percent of three quarters".

Writing out amounts in words is common on checks, contracts, invoices, and legal documents, where the written form confirms the numeric figure. It is also used for teaching children how numbers are named, for preparing voice-over and screen reader scripts where figures should be read aloud in full, and for proofreading written content. For a different way to rewrite numbers, try the Roman numeral converter.

Format switches between a plain number, a currency amount, and a check amount. Plain spells the figure as it stands. Currency names the units, so 1254.30 becomes one thousand two hundred fifty-four dollars and thirty cents, with dollars, pounds, or euros selectable next to it. Check amount uses the bank convention of one thousand two hundred fifty-four and 30/100.

Capitalization offers lowercase, Sentence case, Title Case, and UPPERCASE, which covers the forms used on checks and in contracts. The "and" checkbox switches to British phrasing. The money formats apply when the input is a single figure; inside a sentence, numbers are always spelled out plainly, since naming a currency for every number in a line of text would be wrong more often than right.
