Number to Words Converter: Cardinal, Ordinal & Currency (Free)

Writing out a number in words is one of those small tasks that's surprisingly easy to get wrong — especially for big numbers, where a misplaced "thousand" or a dropped "and" changes the meaning. Whether you're filling in a cheque, drafting a contract, or formatting a document, a number-to-words converter does it correctly and instantly. Here's how to use one and the formats it covers.

The three formats

• Cardinal — the count itself: 1,234 → "one thousand two hundred thirty-four."
• Ordinal — the position: 21 → "twenty-first."
• Currency — the money form: $1,234.50 → "one thousand two hundred thirty-four dollars and fifty cents."

Each has its place, and the right one depends on what you're writing.

It runs in your browser, so it's instant and private.

Where it's needed

• Cheques and financial documents — the amount in words is legally required and must match the figures exactly.
• Contracts and legal text — numbers are often written both as figures and words to prevent tampering or ambiguity.
• Formal writing — many style guides ask you to spell out numbers in certain contexts.
• Accessibility and education — showing how numbers are read aloud.

Why getting it right matters

On a cheque or in a contract, the written-out amount is the authoritative one — if the figures and the words disagree, the words usually win. That makes accuracy non-negotiable, and large numbers are exactly where manual conversion slips. A converter removes the risk: enter the figure, get the exact, correctly-formatted words.

Common questions
