The most common unit used to measure frequency is hertz (Hz), which refers to cycles per second; however, there are some other ways to measure frequency, such as revolutions per minute (RPM) for a motor or beats per minute (BPM) for a person's heartbeat.
hertz. A unit used to measure the frequency of vibrations and waves. One hertz is equal to one cycle per second.Radio waves are usually measured in megahertz, or millions of hertz., pl hertz. 1. (Units) the derived SI unit of frequency; the frequency of a periodic phenomenon that has a periodic time of 1 second; 1 cycle per second.
