Six Hundred and Sixty Thousand in Numbers

How to write 660,000 in words

The number 660,000 is written “six hundred and sixty thousand” in British English. Notice the word “and”: British English places it between the hundreds and the rest of the group. American English usually leaves it out.

Because 660,000 is below one thousand it is a single group: name the hundreds and stop. That gives “six hundred and sixty thousand”.

In running text the number is normally lowercase: “the fee is six hundred and sixty thousand pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Six Hundred and Sixty Thousand. Formal documents often give both forms together, for example “six hundred and sixty thousand (660,000)”, so that a reader can check one against the other.

Six Hundred and Sixty Thousand in figures

To turn “six hundred and sixty thousand” back into digits, work group by group. Each group word (billion, million, thousand) marks a block of three digits. The result is 660,000, or 660000 without separators.

Commas go after every third digit counting from the right: 660,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 660.000, and international scientific style uses spaces: 660 000.

How to write 660,000 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 – “Six hundred and sixty thousand pounds and fifty pence only” for £660,000.50 – or write the pence as a fraction, “Six hundred and sixty thousand pounds 50/100”.
• US check: “Six hundred sixty 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 six lakh sixty thousand only”, with the figure written Tk. 6,60,000/=.

660,000 in British and American English

This is one of the numbers where the two spellings differ. British English keeps “and” after the hundreds; American English generally drops it.

Both are correct in their own country and both are understood everywhere. For a UK cheque, contract or exam, use the British form. See British vs American English numbers for the full comparison.

660,000 in lakh and crore (India, Bangladesh and Pakistan)

In India, Pakistan, Bangladesh and Nepal, large numbers are grouped differently. After the first thousand the digits are grouped in twos, and the units are lakh (100,000) and crore (10,000,000). So 660,000 becomes 6,60,000, read as “six lakh sixty thousand” – or simply 6.6 lakh.

On an Indian cheque or invoice the amount reads “Rupees six lakh sixty thousand only”; in Bangladesh it is “Taka six lakh sixty thousand only”. Our lakh and crore conversion guide explains the system in full.

Common mistakes when writing 660,000

• Dropping “and”. six hundred sixty thousand is American usage. In British English write six hundred and sixty thousand.
• Pluralising the group words. It is hundred, thousand, never “hundreds”, “thousands” or “millions” after a number.
• Using shorthand in formal documents. 660k is fine in a message, but a cheque or contract needs six hundred and sixty thousand or 660,000.
• Miscounting the zeros. 660,000 has 6 digits. Check the commas: every group between commas should have exactly three digits.
