each degree of latitude equals sixty nautical miles, and therefore each
minute of latitude equals one nautical mile...about 1.15 statute miles...if
you want the exact conversion factor let me know.  Each minute of latitude
contains sixty seconds and each second equals 1/60th of a nautical mile.
This is true anywhere on the surface of the Earth.

Your second question:  where can you put a pin anywhere on Earth and find
the latitude and longitude of that spot?  Easy:  Microsoft Encarta 1997
World Atlas CD will do it, but I'd wait for the 1998 version out in the
Autumn.  It's worth the $49.95
