One Hundred Thousand in Numbers

How to write 100,000 in words

The number 100,000 is written “one hundred thousand” in British English.

Because 100,000 is below one thousand it is a single group: name the hundreds and stop. That gives “one hundred thousand”.

In running text the number is normally lowercase: “the fee is one hundred thousand pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: One Hundred Thousand. Formal documents often give both forms together, for example “one hundred thousand (100,000)”, so that a reader can check one against the other.

One Hundred Thousand in figures

To turn “one hundred thousand” back into digits, work group by group. Each group word (billion, million, thousand) marks a block of three digits. The result is 100,000, or 100000 without separators.

Commas go after every third digit counting from the right: 100,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 100.000, and international scientific style uses spaces: 100 000.

How to write 100,000 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 – “One hundred thousand pounds and fifty pence only” for £100,000.50 – or write the pence as a fraction, “One hundred thousand pounds 50/100”.
• US check: “One hundred 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 one lakh only”, with the figure written Tk. 1,00,000/=.

100,000 in British and American English

100,000 is spelled exactly the same way – “one hundred thousand” – in British and American English. The two varieties only differ when a number contains hundreds followed by tens or units, where British English adds “and”. Read more in our guide to British vs American English numbers.

100,000 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 100,000 becomes 1,00,000, read as “one lakh” – or simply 1 lakh.

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

100,000 in Bangla (বাংলায় ১,০০,০০০)

In Bangla, 100,000 is written ১,০০,০০০ using Bengali digits, and in words it is এক লাখ. 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 এক লাখ টাকা মাত্র (“এক লাখ taka only”). In English on the same cheque it is Taka one lakh only – see How to write a cheque in Bangladesh.

Common mistakes when writing 100,000

• Pluralising the group words. It is hundred, thousand, never “hundreds”, “thousands” or “millions” after a number.
• Using shorthand in formal documents. 100k is fine in a message, but a cheque or contract needs one hundred thousand or 100,000.
• Miscounting the zeros. 100,000 has 6 digits. Check the commas: every group between commas should have exactly three digits.
