Anyway, my point is I don't think its fair to call a nation converted when it still has both officially-recognized non-metric units and official uses for them (such as in aviation). I also disagree that these are driven entirely by the US, as Canada still uses a few non-metric units, like the Avery bushel, that the US does not.
From the Wiki article, it sounds as though this is not universally the case any longer: https://en.wikipedia.org/wiki/Metrication_in_Canada#Educatio...
