The number 
.
While one million in the "American" system of numbers means the same thing
as one million in the "British" system, the words billion,
trillion, etc., refer to different numbers in
the two naming systems. Fortunately, in recent years, the "American" system
has become common in both the United States and Britain.
While Americans may say "Thanks a million" to express gratitude, Norwegians offer "Thanks a thousand" ("tusen takk").
