If you have a little explorer/navigator in your blood:

One minute of latitudinal arc = one nautical mile. 1 degree = 60 minutes. 360 degrees * 60 minutes = 21600nm; the approximate circumference of the Earth, in nautical miles. Since there are 6076 feet in a nautical mile, and 60 seconds in a minute, there are approximately 100 feet (101.26 to be exact) per second of arc.

What doesn't make a lot of sense is why folks decided to use a different statute mile. ;) The nautical mile is so convenient.
