A minute of latitude is equal to one nautical mile, or 6076 feet; thus, a second of latitude (6076 divided by 60) is 101 feet, 3 inches.
Conceptually and practically, latitude is the same no matter where you go on earth; however, in reality it varies from 69.41 statute miles per minute at the poles to 68.70 statute miles per minute at the equator due to the earth bulging slightly from its rotational spin.
Finally, 60 degrees North (southern border of the Northwest Territories), a degree of longitude is 34.67 statute miles, 3051 feet (930 meters) per minute, 50.85 feet (15.5 meters) persecond.
