What do the letters MHz and GHz mean?

A Hertz (Hz) is a unit for measuring the frequency of an electromagnetic wave. A hertz is the equivalent of one cycle per second, which means that the wave only oscillates once per second. However, radio waves oscillate at much higher frequency, in the range of Megahertz or Gigahertz. A megahertz (MHz) is the equivalent of 1 million (1,000,000) hertz, and a gigahertz (GHz) is 1 thousand megahertz or 1 trillion hertz (1,000,000,000). MHz and GHz can be converted by moving the decimal point 3 places in the frequency. For instance, a radio transmitter operating at 2.4 GHz is the equivalent of 2400 MHz (moving the decimal point 3 places to the right), and a radio transmitter operating with a frequency of 5000 MHz is equivalent to 5 GHz (moving the decimal point 3 places to the left).
