About speed units

Speed units follow their distance units: miles per hour in the US and UK, kilometers per hour nearly everywhere else, meters per second in physics, and knots (nautical miles per hour) at sea and in the air. A knot is 1.852 km/h exactly, tied to the nautical mile's definition as one minute of latitude. Quick anchors: 60 mph is 96.6 km/h, a 100 km/h motorway limit is 62 mph, and hurricane force starts at 64 knots.
