One Hundred in Numbers

How to Write 100 in Words

The number 100 is written as “one hundred” in British English. When writing numbers on cheques or in formal documents, it is important to use the correct spelling and follow standard British English conventions.

In British English, the word “and” is used between the hundreds and the remainder within the same group. Compound numbers from twenty-one to ninety-nine are hyphenated — for example, thirty-eight or forty-six. The word “and” is not inserted between major groups such as thousands and hundreds.

So the correct way to write 100 in words is: one hundred. This follows the standard rules used in the United Kingdom for cheques, legal documents, and formal writing.
