How to write 30 in words
The number 30 is written “thirty” in British English.
30 is one of the basic number words that every larger number is built from, so it has to be learned rather than constructed.
In running text the number is normally lowercase: “the fee is thirty pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Thirty. Formal documents often give both forms together, for example “thirty (30)”, so that a reader can check one against the other.
