About Kilometers per Hour and Knot

The kilometer per hour is the road speed unit of most of the world, exactly 1/3.6 of a meter per second. Speed limits, car speedometers, and rail and cycling speeds use it outside the US and UK. The knot is one nautical mile per hour, exactly 1.852 km/h. Ships, aircraft, and weather charts use knots because the nautical mile maps onto latitude minutes. One Kilometers per Hour equals 0.5399568044 Knots (1 kph = 0.5399568044 knot). Kilometers per Hour is used in road speed limits outside the US and UK and in car and train speeds. Knot is used in ship and boat speeds.

Precision and Rounding:Most speed factors are exact because they derive from exact length and time definitions (1 mph = 1.609344 km/h precisely); Mach is the exception, since the speed of sound varies with temperature and altitude. The figure used here is 343 m/s, the sea-level value at 20 °C. One decimal place covers driving and running; aviation and ballistics carry more.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
