Two Million One Hundred Thousand in Numbers

How to write 2,100,000 in words

The number 2,100,000 is written “two million one hundred thousand” in British English.

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

1. 2,000,000 is 2 in the millions place, so we write “two million”.
2. 100,000 is 100 in the thousands place, so we write “one hundred thousand”.
3. Join the groups in order, without “and” between them: “two million one hundred thousand”.

In running text the number is normally lowercase: “the fee is two million one hundred thousand pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Two Million One Hundred Thousand. Formal documents often give both forms together, for example “two million one hundred thousand (2,100,000)”, so that a reader can check one against the other.

Two Million One Hundred Thousand in figures

To turn “two million one hundred thousand” 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 2,100,000, or 2100000 without separators.

In expanded form: 2,000,000 + 100,000 = 2,100,000.

Commas go after every third digit counting from the right: 2,100,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 2.100.000, and international scientific style uses spaces: 2 100 000.

How to write 2,100,000 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 – “Two million one hundred thousand pounds and fifty pence only” for £2,100,000.50 – or write the pence as a fraction, “Two million one hundred thousand pounds 50/100”.
• US check: “Two million 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 twenty-one lakh only”, with the figure written Tk. 21,00,000/=.

2,100,000 in British and American English

2,100,000 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 2,100,000 becomes 21,00,000, read as “twenty-one lakh” – or simply 21 lakh.

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

Common mistakes when writing 2,100,000

• Pluralising the group words. It is million, hundred, thousand, never “hundreds”, “thousands” or “millions” after a number.
• Using shorthand in formal documents. 2.1M is fine in a message, but a cheque or contract needs two million one hundred thousand or 2,100,000.
• Miscounting the zeros. 2,100,000 has 7 digits. Check the commas: every group between commas should have exactly three digits.
