Knots (kn) to Miles per hour (mph) Conversion
Knots
The knot is a unit of speed equal to exactly one nautical mile per hour (1.852 km/h), the standard unit for maritime and aerial navigation worldwide. Its name derives from the historical practice of measuring ship speed using a knotted rope thrown overboard. Because the nautical mile is tied to the Earth's geometry (one arcminute of latitude), a ship at 1 knot crosses one arcminute of latitude per hour.
