What do MHz and GHz mean?
1 and megahertz (MHz) are one of the units of fluctuation frequency. The basic unit of fluctuation frequency is hertz, which adopts the thousand system; 1 MHz is equivalent to 1000 KHz, which means 10 6 Hz.
2. GHz, abbreviated as "GHz", is the unit of alternating current or electromagnetic wave frequency, which is equal to one billion hertz (1, 000,000,000 Hz). Gigahertz is the frequency indication unit of ultra-high frequency (UHF) and microwave signals, and the wavelength of electromagnetic wave signal with frequency of 1GHz is 300mm.
Extended data
Unit conversion:
1 kHz？ (kHz 103？ Hertz) = 1 000 Hz
1 MHz (MHz 106？ Hertz) = 1 000 000 Hertz
1 GHz (GHz 109？ Hertz) = 1 000 000 000 Hertz
1 terahertz (terahertz 10 12? Hertz) = 1 000 000 000 000 000 Hz
1 beat (PHz 10 15? Hertz) = 1 000 000 000 000 000 000 Hertz
1 Ai He (EHz 10 18? Hertz) = 1 000 000 000 000 000 000 000 000 000 Hertz
