How do you write one billion pounds in figures?

Answer 1

It depends on whether you are English or American. The traditional English billion is a million-million, while the traditional American billion is a thousand-million.

Thus

English Billion is 1,000,000,000,000

American Billion is 1,000,000,0009

Answer 2

In 1965 a billion was officially defined in the UK (not English) parliament as a thousand million. That was more than 50 years ago so the answer give by "df df" is hopelessly out-of-date! And that ignores the extraneous 9 in his definition of an American billion.

Furthermore, his answer ignores the fact that the question asked about "one billion pounds" - not just "one billion". If it is a billion pounds in mass, the numerical value should be followed by "lbs". If it refers to the UK currency, is should be preceded by GBP. If if refers to a pound currency for some other country, then there are other 3-character codes which identify the currency according to ISO 4217: for example EGP for Egypt, LBP for Lebanon, SDG for Sudan.
