Hertz (Hz)

The hertz (symbol: Hz) is a unit used to measure the frequency of electromagnetic waves. It represents the number of wave-cycles 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
