The hertz (symbol: Hz) is a unit used to measure the frequency of electromagnetic waves.
- Hertz are used when measuring the frequency of wave-cycles of electromagnetic waves.
- One hertz is defined as one cycle per second.
- Hertz measure the number of oscillations of the perpendicular electric and magnetic fields of electromagnetic radiation per second.
-
- 1 Hertz (Hz) = 1 cycle per second
- 1 Kilohertz (kHz) = 1,000 (thousand) cycles per second
- 1 Megahertz (MHz) = 1,000,000 (million) cycles per second
- 1 Gigahertz (GHz) = 1,000,000,000 (billion) cycles per second
- 1 Terahertz (THz) = 1,000,000,000,000 (trillion )cycles per second
