Canada and Latin America use the same 60 Hz system as the U.S. and 100-120 volts. The 50 hertz 220-240 v system is used in Europe and much of the world.

AEG of Germany in 1891 adopted and sold 50Hz systems, Westinghouse in 1890 developed and sold 60Hz systems.

This has nothing to do with systems of weights and measures.
