## About mile per second

The **mile per second** (or **mile/second**) is a unit of speed in the Imperial and US customary systems of units equal to 1,609.344 meters per second (1 mps = 1,609.344 m/s), the derived unit of speed in the International System of Units (SI).

The mile per second (mps) is also equal to about 5,793.6384 kilometers per hour (km/h), or 63,360 inches per second (in/s), or 5,280 feet per second (ft/s) or 3,128.31447 knots (kn).

The speed is the distance traveled by an object during a period of time. Thus, miles per second (or miles/second) show how many miles are traveled in one second. The mile is a unit of length in the Imperial / US customary system of units while the second is the base unit of time in the metric system.
