According to the following website:

1 Statute mile = 5280 feet.
1 Nautical mile = 6076 feet.
Curiously, 1 IRISH MILE = 6719 feet.
As to the question, I'm not a member (I'm always flying the plane, dammit). And with my love of facts, conversions, and stats, I don't get much on the ground, either.
DIVOSH!
