Two Thousand Four Hundred in Numbers

How to write 2,400 in words

The number 2,400 is written “two thousand four hundred” in British English.

The simplest method is to read the figure in groups of three digits from the left and name each group:

1. 2,000 is 2 in the thousands place, so we write “two thousand”.
2. 400 is what remains, written “four hundred”.
3. Join the groups in order, without “and” between them: “two thousand four hundred”.

In running text the number is normally lowercase: “the fee is two thousand four hundred pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Two Thousand Four Hundred. Formal documents often give both forms together, for example “two thousand four hundred (2,400)”, so that a reader can check one against the other.

Two Thousand Four Hundred in figures

To turn “two thousand four hundred” back into digits, work group by group. Each group word (billion, million, thousand) marks a block of three digits, so any block that is missing or short is padded with zeros. The result is 2,400, or 2400 without separators.

In expanded form: 2,000 + 400 = 2,400.

Commas go after every third digit counting from the right: 2,400. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 2.400, and international scientific style uses spaces: 2 400.

How to write 2,400 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 – “Two thousand four hundred pounds and fifty pence only” for £2,400.50 – or write the pence as a fraction, “Two thousand four hundred pounds 50/100”.
• US check: “Two thousand four hundred 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 two thousand four hundred only”, with the figure written Tk. 2,400/=.

2,400 in British and American English

2,400 in Bangla (বাংলায় ২,৪০০)

In Bangla, 2,400 is written ২,৪০০ using Bengali digits, and in words it is দুই হাজার চারশো. 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 দুই হাজার চারশো টাকা মাত্র (“দুই হাজার চারশো taka only”). In English on the same cheque it is Taka two thousand four hundred only – see How to write a cheque in Bangladesh.

Common mistakes when writing 2,400

• Adding “and” between groups. two thousand and four hundred is wrong – “and” only follows the hundreds, never the word thousand or million.
• Pluralising the group words. It is thousand, hundred, never “hundreds”, “thousands” or “millions” after a number.
• Using shorthand in formal documents. 2.4k is fine in a message, but a cheque or contract needs two thousand four hundred or 2,400.
• Miscounting the zeros. 2,400 has 4 digits. Check the commas: every group between commas should have exactly three digits.
