The'''Inverse phrasesecond(s)''' or '''inversereciprocal second(s)''', by(s⁻¹) referringis toa unit of [[frequency]], defined as the [[multiplicative inverse]] of the [[second]] (a unit of time),. providesIt theis [[denominatordimensional analysis|dimensionally]] forequivalent a rate, the most important of which are the followingto:

* [[Cycles per second]]

* [[Hertz]] (the SI unit for periodic cycles per second)

* [[Becquerel]]s (the SI unit for aperiodic or stochastic events per second)

It also provides the [[denominator]] for a [[Rate (mathematics)|rate]], the most important of which are the following:

* [[Cycles per second]]

* [[Radians per second]]

*''"The SI unit of frequency is given as the hertz, implying the unit cycles per second; the SI unit of angular velocity is given as the radian per second; and the SI unit of activity is designated the becquerel, implying the unit counts per second. Although it would be formally correct to write all three of these units as the reciprocal second, the use of the different names emphasises the different nature of the quantities concerned."'' {{cite web |url=http://www.bipm.org/en/publications/si-brochure/section2-2-2.html |title=Units with special names and symbols; units that incorporate special names and symbols }}
