We use 0.25 statute mile in US

Question:

What is a US Statute Mile in terms of feet or metres?
The term "Mile" is ambiguous. *There are lots of different "miles",
for instance there are theoretically an infinite number
of different lengths of Nautical Mile ....

But only one definition of a Metre, and therefore a Kilometre.

This is one reason why IGC has always used metric units
for International definitions (Badge distances, for instance),
and science uses the SI system which is basically metric
(I stand by to be corrected on this statement).

Ian,

Most aircraft in the US use the Nautical System, ie Commericial,
Military and most private aircraft. 1 Nautical mile = 1 second of
latitude, 60 nautical miles = 1 degree of latitude.
