How to write 8,500,000,000 in words
The number 8,500,000,000 is written “eight 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:
- 8,000,000,000 is 8 in the billions place, so we write “eight billion”.
- 500,000,000 is 500 in the millions place, so we write “five hundred million”.
- Join the groups in order, without “and” between them: “eight billion five hundred million”.
In running text the number is normally lowercase: “the fee is eight billion five hundred million pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Eight Billion Five Hundred Million. Formal documents often give both forms together, for example “eight billion five hundred million (8,500,000,000)”, so that a reader can check one against the other.

Eight Billion Five Hundred Million in figures
To turn “eight 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 8,500,000,000, or 8500000000 without separators.
In expanded form: 8,000,000,000 + 500,000,000 = 8,500,000,000.
Commas go after every third digit counting from the right: 8,500,000,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 8.500.000.000, and international scientific style uses spaces: 8 500 000 000.

Common mistakes when writing 8,500,000,000
- Pluralising the group words. It is billion, hundred, million, never “hundreds”, “thousands” or “millions” after a number.
- Using shorthand in formal documents. 8.5bn is fine in a message, but a cheque or contract needs eight billion five hundred million or 8,500,000,000.
- Miscounting the zeros. 8,500,000,000 has 10 digits. Check the commas: every group between commas should have exactly three digits.
