Numbers in words, zero to one million
These are the rows worth reading rather than converting: every number from zero to twenty, the tens, and the round scale words. Note where the hyphen falls — twenty-one through ninety-nine take one, and nothing else does. For anything not listed, type it into the box above.

About Number to Words
Confileo's Number to Words tool converts a number into words and words back into a number, in both directions at once. Everything runs in your browser, free and without signup, and your files are deleted automatically after processing.
Almost nobody converts a number to words for fun. They are writing a cheque, an invoice, a contract or a legal filing — documents where the amount appears twice, once in figures and once spelled out, so that a stray digit cannot quietly change what is owed. The duplication is not decoration: in both UK and US practice, where the words and the figures disagree, the words are the binding version. This page converts in both directions at once — digits on the left, words on the right.
The one real decision in English is the word "and". British usage puts it before the final part below one hundred: one hundred and twenty-three, one thousand and forty, two thousand and five. American usage omits it — one hundred twenty-three, one thousand forty. Neither is an error; each is standard where it is used. What does look wrong is switching between the two inside one document, so the form is a switch you set once rather than a decision you retake on every line.
The punctuation rules are narrower than people expect. Every compound number from twenty-one to ninety-nine is hyphenated — forty-two, seventy-nine — and nothing else in the written form is. There is no comma, however long the number gets, even though the digits carry one every three places. "A hundred" is fine in speech, but formal documents use "one hundred", which is why cheques are written that way. "Twelve hundred" for 1200 is ordinary English, but it is not the form to put on a legal amount; that is one thousand two hundred.
Decimals are read digit by digit after the point: 3.14 is three point one four, not three point fourteen, and 0.5 is zero point five. A negative is prefixed with minus. On the input side, the page reads the number the way English reads it. 1.234 here is one point two three four, while the same string in the German version of this converter reads as one thousand two hundred thirty-four, because a full stop is the German thousands separator. Commas used as thousands separators are accepted, so 1,234 and 1234 read the same.
English runs on the short scale: a billion is a thousand million, a trillion is a thousand billion. That is worth knowing before trusting a translated figure. German Billion means a million million, and the German word for a thousand million is Milliarde, so a number carried across the two languages without checking is out by a factor of a thousand. Britain abandoned the long scale for official use in 1974, so British and American billions have agreed for more than fifty years; documents older than that may not.
The reverse direction shares the page: type the words into the right-hand box and the digits appear on the left, which is what you want when checking a cheque someone else wrote. Hyphens and the British "and" are both read, so one thousand and forty and one thousand forty both give 1040. Everything runs in your browser — nothing is uploaded, no account.

Number to Words — Frequently asked questions
How do you write 1234 in words?
One thousand two hundred thirty-four in American usage; one thousand two hundred and thirty-four in British. The hyphen in thirty-four is not optional — every compound number from twenty-one to ninety-nine takes one. There is no comma anywhere in the written form, even though the digits carry one, and no "and" between the thousand and the hundred.
Is it one hundred and one or one hundred one?
Both are correct, in different places. British English puts "and" before the final part below one hundred — one hundred and one, one thousand and forty. American English leaves it out: one hundred one. Neither is wrong, but mixing the two inside one document is visible. The switch here picks the form, so a UK cheque and a US invoice can both be written from one place.
How do I write the amount in words on a cheque?
Write the amount in words on the line, then rule out the space left over so nothing can be added. US checks put the cents as a fraction over 100 — One thousand two hundred thirty-four and 50/100. UK cheques spell the pounds, add the pence and end with "only". Either way, the words are what the bank pays on: where words and figures disagree, the words govern — Bills of Exchange Act 1882 in the UK, UCC 3-114 in the US.
How do you say 3.14 in words?
Three point one four. A decimal is read digit by digit after the point, not as a number, so 3.14 is never three point fourteen, and 0.5 is zero point five. This page follows that, and it handles a leading minus — minus three point one four — and a thousands comma in the input, so 1,234.5 and 1234.5 give the same reading.
Can it convert words back into numbers?
Yes — type the words into the right-hand box and the digits appear on the left. Hyphens and the British joining "and" are both read, so "one thousand and forty" and "one thousand forty" both give 1040. The two panes stay linked, so you can type into either one and watch the other follow, which is the quick way to check an amount someone else has written out.
