For checks, invoices, receipts and contracts

Some documents ask for an amount in words as well as in figures, because words are harder to alter and settle any doubt about a number that is smudged or badly written. A check has a whole line for the amount in words. Receipts and invoices often repeat the total in words, and contracts, promissory notes, loan agreements, leases and deeds usually write important sums both ways.

Spelling out a long number is surprisingly easy to get wrong: is it “forty” or “fourty”, where do the hyphens go, how do you say 1,000,050? This tool writes it for you, ready to copy, so you only need to read it once before signing.

Three formats

Number writes the figure in words: 2,450 becomes “two thousand four hundred fifty”. If you type decimals, they are read digit by digit after “point”, so 3.75 becomes “three point seven five”. It suits legal and academic texts, teaching, and any document where numbers are spelled out.

Amount with currency adds the currency and the cents: 1,250.75 in dollars becomes “one thousand two hundred fifty dollars and seventy-five cents”. You can choose US dollars, euros or pounds sterling, with pence for pounds.

Check or invoice writes the whole part in words and the cents as a fraction over 100, the style printed on most checks: “One thousand two hundred fifty and 75/100 dollars”. Numbers can go up to 999,999,999,999 with two decimals, enough for any personal or business document.

Roman numerals too

For whole numbers from 1 to 3999, the tool also shows the number in Roman numerals. That is handy for chapter and section numbers, outlines, event editions, sequels, clock faces, building inscriptions and years on title pages: 2027 becomes MMXXVII, for example.

The Spanish and Portuguese versions of ConvertirDocs write numbers in those languages, with their own currencies such as pesos, soles, bolívares or reais, and the Mexican “M.N.” ending on checks. Switch the site language if you need an amount in one of them, for a bilingual contract or an invoice for a client abroad.

Private and free

The conversion happens in your browser. The amounts you type are not sent to a server and are not saved, which is how it should be with figures from invoices, salaries or contracts. It is free, with no account and no limit, on a phone or a computer.

Before signing or sending, read the amount in words once more next to the figures. If your bank, your accountant or a contract template requires a particular wording, such as adding “only” at the end of a check line, follow that wording.
