Numbers To Words

Convert numbers to English words, or words back to numbers.

Enter a number to convert it to the word version, or paste English number words (e.g. THREE HUNDRED FIFTY-FOUR TRILLION...) to convert them back to digits. Handles values up to a nonillion (1 followed by 30 zeros). Hyphens, commas, and the word "and" are ignored when parsing words.
