What is a UK billion?
A UK billion is a US trillion. In the UK folks count to a
thousand million, 999 thousand million, before they move on up to a
Many people in the UK are beginning to adopt the US method of counting. The US system is not as logical, but it is easier.
The same as a billion in the US. A thousand million. However, a long time ago, a 'British billion' was a million million, ie. a thousand times bigger than a US billion. The term 'billiard' is sometimes used to mean 'British billion' to clear up the confusion. Everybody in the UK uses the same definition as in the US though.
Depending on the term billion (UK or US - Long vs short). US - 1,000,000,000 /2 = 500,000,000 UK - 1,000,000,000 /2 = 500,000,000,000 In the US a billion is a thousand million whereas the UK and most of Europe the value is a million million. Why? Probably US millionaires wanted to be exclusive. See related link.
Yes, one billion represents the same number in both countries. Now it does. But in the past, in the UK, 1 billion was 1,000,000,000,000. In the US 1 billion was 1,000,000,000. (The British called the American 1 billion one thousand million.) The UK has now adopted the American system, so it is the same in both countries.
