- Hertz (the SI unit for cycles per second)
- Becquerels (the SI unit for aperiodic or stochastic radionuclide events per second)
- Shear rate (the velocity gradient in a fluid)
- "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." "Units with special names and symbols; units that incorporate special names and symbols".
- "(d) The hertz is used only for periodic phenomena, and the becquerel (Bq) is used only for stochastic processes in activity referred to a radionuclide." "BIPM - Table 3". BIPM. Retrieved 2012-10-24.
