Number to Words Converter

What is it?

A number to words converter translates a numeric value into its written English (or other language) equivalent. The number 1,492 becomes "one thousand, four hundred and ninety-two". The process seems simple for small numbers, but quickly becomes error-prone for large values: how do you write 1,000,000,000 in words? Or 3,750,250.75 as a currency amount on a cheque? This free online converter handles integers from zero up to 999 trillion (999,999,999,999,999) and supports three output formats for each of six languages: **Cardinal** — the standard written form: "two hundred and fifty-three". **Ordinal** — the positional form: "two hundred and fifty-third". **Currency** — the cheque-writing form: "two hundred and fifty-three euros and forty-two cents" (with a currency selector for EUR, USD, GBP, CHF and more). Supported languages: English, Italian, French, German, Spanish and Portuguese — all following their respective grammatical rules, including French quatre-vingts, German compound numbers and Italian elision rules.

How to use it

7. For decimal numbers in Currency mode, enter the value with a decimal point (e.g. 253.42).

Why use this tool

Writing numbers in words is required in a surprisingly wide range of everyday situations. Legal documents and contracts spell out monetary values in full to prevent fraud and ambiguity — a cheque for "$1,234.56" also writes "one thousand two hundred thirty-four dollars and 56/100" to make alteration impossible. Bank transfers, invoices, formal letters, academic papers, style guides (most demand that numbers under a hundred are written out), and formal writing in many languages all require this skill. For non-native speakers or when writing in a second language, producing the correct ordinal form or the correct gender agreement in French or Spanish is genuinely tricky. Our tool handles all the grammatical edge cases automatically: French "quatre-vingt-dix-neuf" (99), German "einundzwanzig" (21), Italian "ventuno" (21 with elision), and Spanish "veintiuno". The currency mode is particularly handy for accountants, freelancers filling in invoices and anyone who needs to write cheques: it formats the amount exactly as banks and legal documents require, in the correct language.
