The SI unit of frequency is the hertz (abbreviated Hz), named after the German physicist Heinrich Hertz. A previous name for this unit was cycles per second (cps). The SI unit for period is the second. A traditional unit of measure used with rotating mechanical devices is revolutions per minute, abbreviated r/min or rpm. 60 rpm equals one hertz.
