{{Short description|A unit of frequency}}

The '''inverse second''', '''reciprocal second''', or '''perreciprocal second''' (s⁻¹) is a [[unit of measurement|unit]] of [[frequency]], defined as the [[multiplicative inverse]] of the [[second]] (a unit of time). It is [[dimensional analysis|dimensionally]] equivalent to:

* the unit [[hertz]] – the SI unit for [[frequency]]

* the unit [[radian per second]] – the SI unit for [[angular frequency]] and [[angular velocity]]

* the unit [[becquerel]] – the SI unit for the rate of occurrence of aperiodic or stochastic [[radioactivity|radionuclide]] events per second

* the unit [[baud]] – the unit for [[symbol rate]] over a communication link

* the unit of [[strain rate]] – the velocity gradient (comprising the [[shear rate]] and directional expansion rate) of a fluid or solid.
