Ian,

Paul didn't really answer your question. A Statute Mile in the USA is
defined as 5,280 feet. The Nautical Mile length in feet isn't as
clear, as you point out. I've seen 6,080 feet, 6,076 feet and 6000
feet.

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).
