Hi Ian,

The term "Statute" clarifies the type of "miles". It is different from a
nautical mile. US Contests use Statute Miles because Americans are used to
driving distances in statute miles. You can find conversions he

Like many Americans - I prefer the metric system as well. Much of my
college engineering education was done using metric units.

Good Soaring,

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).
