Frequency is defined as the rate at which an event occurs during a given period of time. With a vibration, the event is a cycle and the period of time is 1 second. Thus, frequency is expressed in cycles per second.
The proper term for cycles per seconds is Hertz (Hz). This is the most common way to measure frequency. Multiply the Hertz by 60 to get the cycles or revolutions per minute (RPM).
