Trillion

In the American system, one trillion equals 10^(12)=1000000000000. In the French and German systems, one trillion equals 10^(18).

In recent years, the "American" system has become common in both the United States and Britain. In the words of The Chicago Manual of Style, "The American definitions are gaining acceptance, but writers need to remember the historical geographic distinctions." This use of a common meaning for "trillion" constitutes a fortunate development for standardization of terminology, albeit a somewhat regrettable development from the point of view that the British convention for representing large numbers is simpler and more logical than the American one.
