Number to Words Converter

This tool writes numbers in words: 1234 becomes one thousand two hundred thirty-four. Type one number on each line, with or without thousands separators, and the words appear as you type, for whole numbers up to 999 trillion, for decimals and for negative numbers. Choose “Amount of money” to write a sum with its currency, such as forty-two dollars and fifty cents, and “As on checks and invoices” for the form used on checks, contracts and bank documents: One thousand two hundred thirty-four dollars and 56/100.

The converter follows the rules of each of its 23 languages, so it can also write numbers in a language you don't speak: choose it in the list, whatever the language of this page. German writes a number as one word, zweitausendsechsundzwanzig for 2026, French says quatre-vingt-dix for 90, Russian and Polish change the name of the currency with the number, and Chinese, Japanese and Korean count in groups of ten thousand. Everything happens in your browser, and nothing you type is sent anywhere.
