How to write 51,000 in words

The number 51,000 is written “fifty-one thousand” in British English. The hyphen in fifty-one is not optional – every compound number from twenty-one to ninety-nine is hyphenated.

Because 51,000 is below one thousand it is a single group: name the hundreds and stop. That gives “fifty-one thousand”.

In running text the number is normally lowercase: “the fee is fifty-one thousand pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Fifty-One Thousand. Formal documents often give both forms together, for example “fifty-one thousand (51,000)”, so that a reader can check one against the other.

Common mistakes when writing 51,000

  • Missing the hyphen. fifty one thousand is a very common misspelling. Write fifty-one thousand.
  • Pluralising the group words. It is thousand, never “hundreds”, “thousands” or “millions” after a number.
  • Using shorthand in formal documents. 51k is fine in a message, but a cheque or contract needs fifty-one thousand or 51,000.
  • Miscounting the zeros. 51,000 has 5 digits. Check the commas: every group between commas should have exactly three digits.
