One megahertz (abbreviated: MHz) is equal to 1,000 kilohertz, or 1,000,000 hertz. It can also be described as one million cycles per second. Megahertz is used to measure wave frequencies, as well as the speed of microprocessors. Radio waves, which are used for both radio and TV broadcasts, are typically measured in megahertz.
Kilohertz. A kHz, or Kilohertz, is a measurement of frequency equal to 1,000 hertz. Kilohertz is unit of measurement for alternating current, audio signals, and a measurement of wireless signals.
