Ashmo said:In English it tends to be a bit easier to use the shorter scale because "billiard" makes merkins think you're talking about a game of Pool.
Also, the shorter scale makes numbers sound bigger to those accustomed to the longer one. That's always good for dramatisation.
Uhm, actually, it IS an England - USA thing. The English do say Billiard, the Americans don't. From the dict;
bil·lion Pronunciation (blyn)
n.
1. The cardinal number equal to 10^9.
2. Chiefly British The cardinal number equal to 10^12.
3. An indefinitely large number.
And as usual the Americans follow the LEAST logical path...
million: single million
billion: a million times a million. "Bi" refers to two, as in a million squared.
trillion: a million times a million times a million. "Tri" refers to three.
Not only logical, but also the normal way it was established 15th century BC, whereas the whole smaller scale thing the Americans use was actually a minority phenomenon in the 17th century BC.
But you know the yanks, the smaller the better. Small words for small minds.
PS: the thing being here, in answer to the original question, that 2 trillion USD is 2 000 000 000 000, in Britain 2 trillion BP is 2 000 000 000 000 000 000. Cool, no?
