Forty-Five Million in Numbers

How to write 45,000,000 in words

The number 45,000,000 is written “forty-five million” in British English. The hyphen in forty-five is not optional – every compound number from twenty-one to ninety-nine is hyphenated.

Because 45,000,000 is below one thousand it is a single group: name the hundreds and stop. That gives “forty-five million”.

In running text the number is normally lowercase: “the fee is forty-five million pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Forty-Five Million. Formal documents often give both forms together, for example “forty-five million (45,000,000)”, so that a reader can check one against the other.

Forty-Five Million in figures

To turn “forty-five million” back into digits, work group by group. Each group word (billion, million, thousand) marks a block of three digits. The result is 45,000,000, or 45000000 without separators.

Commas go after every third digit counting from the right: 45,000,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 45.000.000, and international scientific style uses spaces: 45 000 000.

How to write 45,000,000 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 – “Forty-five million pounds and fifty pence only” for £45,000,000.50 – or write the pence as a fraction, “Forty-five million pounds 50/100”.
• US check: “Forty-five million 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 four crore fifty lakh only”, with the figure written Tk. 4,50,00,000/=.

45,000,000 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 45,000,000 becomes 4,50,00,000, read as “four crore fifty lakh” – or simply 4.5 crore.

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

Common mistakes when writing 45,000,000

• Missing the hyphen. forty five million is a very common misspelling. Write forty-five million.
• Pluralising the group words. It is million, never “hundreds”, “thousands” or “millions” after a number.
• Using shorthand in formal documents. 45M is fine in a message, but a cheque or contract needs forty-five million or 45,000,000.
• Miscounting the zeros. 45,000,000 has 8 digits. Check the commas: every group between commas should have exactly three digits.
