🔤Number to Words

About this number to words converter

Type a figure and get it spelled out every way you are likely to need it: plain words, Title Case, uppercase, cheque format, currency wording, and the ordinal form. Click any line to copy it.

Very large numbers stay exact — the arithmetic uses arbitrary-precision integers rather than floating point, so an eighteen-digit figure does not quietly lose its last few digits the way a naive converter would.

Writing a cheque or an invoice

The amount line on a cheque exists to make tampering obvious. A written "One Thousand Two Hundred Thirty-Four Dollars" cannot be turned into ten thousand with a stroke of a pen, whereas the boxed figure can — which is why banks pay the written amount when the two disagree.

Cents are written as a fraction over one hundred rather than in words, and the word "only", or a drawn line, fills the rest of the line so nothing can be added after it. American usage drops the "and" before the tens; British usage keeps it. Both are accepted everywhere.

Billions, and the two systems

A billion means a thousand million on the short scale, used in English throughout the world today. Historically the long scale — where a billion was a million million — was standard in Britain and remains standard in much of continental Europe, so a French billion is an English trillion.

This converter uses the short scale, which is what English-language finance, journalism and government all use. If you are converting figures across languages, the difference is a factor of a thousand and worth checking. For the reverse direction — a written amount you need as digits — the text counter is often what people reach for next when checking a document.
