Numbers
Number to Words Converter
Used by developers, writers, and creators worldwide.
A number to words converter writes a whole number out in plain English — turning 1234 into "one thousand two hundred thirty-four". Spelling numbers out is exactly what you do on cheques, in legal and financial documents, and in formal writing, where a written-out amount removes any doubt about the figure. Doing it by hand for large numbers is fiddly and easy to get wrong, especially around the hundreds and the hyphenated tens. This tool handles numbers up to the hundreds of billions, including negatives and zero, and produces the correct wording instantly. Type a number and copy the words. It is ideal for writing cheques, drafting contracts, filling in forms, teaching place value, and adding number words to documents. Because it follows standard English conventions, the wording is the conventional form you would write yourself, only faster.

FAQ
how large a number can it handle
It converts whole numbers up to 999,999,999,999 — just under a trillion — including zero and negative numbers. That covers cheques, invoices, and almost any everyday or business figure you might need to write out.
does it add hyphens correctly
Yes. Compound numbers from twenty-one to ninety-nine are written with a hyphen, following standard English style, so you get "forty-two" rather than "forty two". Hundreds, thousands, and larger groups are spaced conventionally.
why write numbers in words
Words remove ambiguity, which is why cheques, contracts, and legal documents spell amounts out alongside the digits. It also helps when teaching place value or when a figure must be impossible to alter or misread.
