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.
Other units of frequency are the kHz, equal to 1,000 Hz or 0.001 MHz, and the gigahertz, equal to 1,000,000,000 Hz or 1,000 MHz. The bandwidth of a digital signal, in megahertz, is related to the data speed in bits per second.
