Title: Nautical mile explained Written by: duddy on Dec 8, 2014 (https://biology-forums.com/gallery/47/4_08_12_14_4_18_52.jpeg) (https://biology-forums.com/index.php?action=gallery;sa=view;id=19510) Every ship sails a mile a minute. A nautical mile is one minute of arc measured along any meridian. In other words, a nautical mile is based on the circumference of the planet Earth. If you were to cut the Earth in half at the equator, you could pick up one of the halves and look at the equator as a circle. You could divide that circle into 360 degrees. You could then divide a degree into 60 minutes. A minute of arc on the planet Earth is 1 nautical mile. This unit of measurement is used by all nations for air and sea travel.
