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.
Gigahertz, generally abbreviated GHz, refers to frequencies in the billions of cycles per second range. Giga is the standard multiplier for 1 billion, and Hertz is the standard unit for measuring frequencies, expressed as cycles or occurrences per second. One GHz is equivalent to 1,000 megahertz (MHz). Most commonly, gigahertz is used when discussing computer performance or radio frequencies.
