The present definition of the nautical mile is 1852 meter exactly.
The present definition of the statute mile is 1609.344meter exactly.

There are lots of archaic measures, many or perhaps most only used localley that have been abondonned for the world wide system of metrics.

Because Brittania ruled the waves?
VC> They created UTC, same thing but they define it differently I think.
UTC was not cerated by the French but was a joined effort from scientists all over the world united in the International Bureau of Wights and Measures.
UTC is NOT the same thing as GMT. GMT is based on mean solar time UTC is based on the atomic clocks.
VC> Too many years ago when I had to study this stuff.
It has been a long time for me as well. Wikipedia is my friend.
