{{Short description|Unit of speed or velocity}} The '''inch per second''' is a unit of speed or velocity. It expresses the distance in inches (in) traveled or displaced, divided by time in seconds (s). The corresponding coherent SI unit is the metre per second.<ref name="efunda"/>

== Uses == In magnetic tape sound recording, magnetic tape speed is often quoted in inches per second (abbreviated "ips").
In computer mice sensitivity is also often referred to in inches per second (abbreviated as "ips").
In rotorcraft health monitoring, rotor and shaft induced vibration levels are often quoted in inches per second.
