n. pl. hertz
A unit of frequency equal to 1 cycle per second.
The SI derived unit used to measure the frequency of vibrations and waves, such as sound waves and electromagnetic waves. One hertz is equal to one cycle per second. The hertz is named after German physicist Heinrich Hertz (1857-1894).
The international unit of frequency: one cycle per second. The abbreviation for hertz is Hz.
