The Nautical mile - What is it?
In this video we discuss the relationship between the size of the earth and the nautical mile. A nautical mile is equal to one minute of latitude, which is equivalent to one sixtieth of a degree of latitude. If we know the circumference of the earth, we can find the length of a nautical mile.
