About Speed Units

Kilometres per hour is the road-speed unit in most countries; the US and UK use miles per hour. Knots (one nautical mile per hour) are used at sea and in aviation. Mach expresses speed as a multiple of the speed of sound, which depends on air temperature; this converter uses 340.3 m/s, the value for the standard atmosphere at sea level (15 °C).
