To be fair, also in Europe imperial measurements are still used, for example in plumbing, where inches are used for some reasons still unknown, or in aviation, where they continue to measure, in part, in feet. In nautical matters it is a separate issue, measuring in knots and nautical miles, and has nothing to do with metric measurements either.

The ICAO has apparently recommended using the international system of units since 2010, but it hasn't been widely adopted yet.
