I don't think that's right. 10^6 is a million in both languages.

10^9 used to be a milliard in British English but is no longer used. It is now referred to as a billion.

10^12 used to be a billion in British English but is now referred to as a trillion.

Edit: http://www.youtube.com/watch?v=C-52AI_ojyQ explains it all quite nicely.
