“How do we measure distance while traversing the ocean?”
One of the most important pieces of information needed for transportation is the distance that one needs to cross. This fact holds regardless if it’s by land, sea or air. Speaking about the sea, have you ever wondered how people measure distance when they are out on the ocean? Well, after many centuries of improvements, navigators have created the unit of the Nautical mile for traversing aquatic distances. Despite sounding like a unit based on the imperial system, the nautical mile is actually an SI-based quantity, with one NM being equal to 1852 meters.  This unit is so fundamental to navigation that not only has the field of aviation begun using it, but that the unit for aquatic speed, the knot, is equal to one nautical mile per hour!
