Hertz

n. unit of frequency equal to one cycle per second (Physics)

n. family name; Heinrich Rudolph Hertz (1857-1894), German physicist, first person who produced electromagnetic waves in an artificial manner

The hertz (symbol: Hz) is the SI unit of frequency. Its base unit is cycle/s or s-1 (also called inverse seconds, reciprocal seconds). In English, hertz is used as both singular and plural. As any SI unit, Hz can be prefixed; commonly used multiples are kHz (kilohertz, 103 Hz), MHz (megahertz, 106 Hz), GHz (gigahertz, 109 Hz) and THz (terahertz, 1012 Hz).
