What number does the word billion represent in England?

Answer 1

The English billion, a redundant measure, is 1,000,000,000,000 (ie. a million million). Its use dimished following the advent of computers and the internet, as the American billion, 1,000,000,000 came into common usage.

At present, in England, the word billion means 1,000,000,000 (ie. a thousand million) = 109.

The move is often thought to be related to the use of the standard scientific (SI) units, which use prefixes that increase by products of one thousand, giving a new numerical measure for each prefix.
