Speed units combine a distance with a time. The most common are kilometers per hour (road speeds in most countries), miles per hour (US and UK roads), meters per second (physics and engineering) and knots (aviation and shipping). One knot is one nautical mile per hour, about 1.852 km/h. Mach numbers relate speed to the speed of sound.
