## About millimeter per second

The **millimeter per second** is a unit of speed in the metric system equal to 0.001 meters per second (1 mm/s = 0.001 m/s), the derived unit of speed in the International System of Units (SI).

The millimeter per second (mm/s) is also equal to about 0.0036 kilometers per hour (km/h), or 0.0022369 miles per hour (mph), or 0.00328 feet per second (ft/s), or 0.1 centimeters per second (cm/s) or 0.03937 inches per second (in/s).

The speed is the distance traveled by an object during a period of time. Thus, millimeters per second (millimeters/second) show how many millimeters are traveled or displaced in one second. The millimeter is a unit of length in the metric system while the second is a unit of time.

Symbol: mm/s

Plural: millimeters per second

Also known as: millimetre/second, millimetre per second (plural: millimetres per second, Int. spelling), millimeter/second (plural: millimeters/second, US spelling)
