>Are feet and NM not part of the standard Imperial units of measure? In addition to the other replies you're getting here, the US for instance does not use imperial units, despite what many people on the internet believe. Imperial units are used by the UK (hence the term "imperial"). The US uses "US customary units", which sometimes overlap with UK units, and other times have the same name but are different. An imperial gallon is quite different from a US gallon, for instance, but imperial and US inches are the same.
