Notes
An international unit in navigation. The name knot came from the ships' log lines that are marked off by knots tied to the rope at intervals of roughly 47 feet apart. The speed of a ship, in nautical miles per hour, was then estimated by counting the number of knots that the ship has passed in 28 seconds after the rope has been tossed overboard.
 1 knot = 1 naut. mile/h = 1852 m/h = 6080 ft/h
