How to write 1,500,000,000 in words

The number 1,500,000,000 is written “one billion five hundred million” in British English.

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

  1. 1,000,000,000 is 1 in the billions place, so we write “one billion”.
  2. 500,000,000 is 500 in the millions place, so we write “five hundred million”.
  3. Join the groups in order, without “and” between them: “one billion five hundred million”.

In running text the number is normally lowercase: “the fee is one billion five hundred million pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: One Billion Five Hundred Million. Formal documents often give both forms together, for example “one billion five hundred million (1,500,000,000)”, so that a reader can check one against the other.

One Billion Five Hundred Million in figures

To turn “one billion five hundred million” 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 1,500,000,000, or 1500000000 without separators.

In expanded form: 1,000,000,000 + 500,000,000 = 1,500,000,000.

Commas go after every third digit counting from the right: 1,500,000,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 1.500.000.000, and international scientific style uses spaces: 1 500 000 000.

How to write 1,500,000,000 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.

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.

1,500,000,000 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 1,500,000,000 becomes 1,50,00,00,000, read as “one hundred and fifty crore” – or simply 150 crore.

Common mistakes when writing 1,500,000,000

  • Pluralising the group words. It is billion, hundred, million, never “hundreds”, “thousands” or “millions” after a number.
  • Using shorthand in formal documents. 1.5bn is fine in a message, but a cheque or contract needs one billion five hundred million or 1,500,000,000.
  • Miscounting the zeros. 1,500,000,000 has 10 digits. Check the commas: every group between commas should have exactly three digits.
