Common Speed Units
Speed is the rate at which an object covers distance. The most common units for road vehicles are Kilometers per hour (km/h) used globally, and Miles per hour (mph) used primarily in the United States and the United Kingdom.
In science and physics, the standard SI unit is Meters per second (m/s). In aviation and maritime navigation, Knots (nautical miles per hour) and Mach (the speed of sound) are widely used.
