Miles per hour
Miles per hour (mph) is the unit of speed used in road transport in the United States, United Kingdom, and a small number of other countries. One mile per hour equals approximately 1.60934 km/h or 0.44704 m/s. Speed limits on US interstate highways are commonly 65–75 mph, while the UK national speed limit is 70 mph.
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.
