Eighteen Thousand in Numbers

How to write 18,000 in words

The number 18,000 is written “eighteen thousand” in British English.

Because 18,000 is below one thousand it is a single group: name the hundreds and stop. That gives “eighteen thousand”.

In running text the number is normally lowercase: “the fee is eighteen thousand pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Eighteen Thousand. Formal documents often give both forms together, for example “eighteen thousand (18,000)”, so that a reader can check one against the other.

Eighteen Thousand in figures

To turn “eighteen thousand” back into digits, work group by group. Each group word (billion, million, thousand) marks a block of three digits. The result is 18,000, or 18000 without separators.

Commas go after every third digit counting from the right: 18,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 18.000, and international scientific style uses spaces: 18 000.

How to write 18,000 on a cheque

Banks read the amount in words as the legal amount, so it must be exact. Write the pounds in words, add the word pounds, and finish with only so that nothing can be added afterwards.

• With pence: add the pence after the pounds – “Eighteen thousand pounds and fifty pence only” for £18,000.50 – or write the pence as a fraction, “Eighteen thousand pounds 50/100”.
• US check: “Eighteen thousand and 00/100 dollars”. American cheques drop the “and” after the hundreds and put it before the cents.
• Bangladesh, India and Pakistan: the currency word comes first and the amount is counted in lakh and crore – “Taka eighteen thousand only”, with the figure written Tk. 18,000/=.

18,000 in British and American English

18,000 in Bangla (বাংলায় ১৮,০০০)

In Bangla, 18,000 is written ১৮,০০০ using Bengali digits, and in words it is আঠারো হাজার. Bangla has its own word for every number from one to ninety-nine, and above that it counts in হাজার (thousand), লাখ (lakh) and কোটি (crore), the same grouping used across Bangladesh and India.

On a cheque or invoice written in Bangla the amount reads আঠারো হাজার টাকা মাত্র (“আঠারো হাজার taka only”). In English on the same cheque it is Taka eighteen thousand only – see How to write a cheque in Bangladesh.

Common mistakes when writing 18,000

• Pluralising the group words. It is thousand, never “hundreds”, “thousands” or “millions” after a number.
• Using shorthand in formal documents. 18k is fine in a message, but a cheque or contract needs eighteen thousand or 18,000.
• Miscounting the zeros. 18,000 has 5 digits. Check the commas: every group between commas should have exactly three digits.
