I’m from the EU (Spain), they are 100% in the metric system, but the Imperial system is certainly difficult to kill, for reasons I don’t know, used in Nautics, Air Traffics and curiously also in Plumbing, where tubes are still in inches. The biggest drawback in the Imperial system is that it leads to errors (NASA crashed 2 Mars probes because of it, before changing to the metric system), it’s because the different units don’t have any relations among these and are complete arbitrarily, which difficult a lot of precise calculations. Never was a good idea to use the bodyparts of a death King as measure units.
