A gigahertz is a frequency unit equal to one billion hertz.
Gigahertz became common as wireless, microwave, radar, and computing systems moved into billion-cycle operating ranges.
GHz is used for Wi-Fi bands, microwave systems, radar, satellite links, processor clocks, and high-frequency electronics.
A megahertz is a frequency unit equal to one million hertz.
Megahertz became common as radio, electronics, communication, and computing frequencies reached millions of cycles per second.
MHz is used for radio bands, oscillators, microcontrollers, communication systems, processor clocks, and electronic test equipment.
Mathematically, megahertz (MHz) = gigahertz (GHz) converted with the formula below.
1 GHz = 1,000 MHz
1 MHz = 0.001 GHz
Formula: value × 1000
Example: 15 GHz = 15,000 MHz
Precision note: Use the exact relationship 1 GHz = 1000 MHz. Preserve meaningful precision for tuned, regulated, or measured frequencies.
1 GHz = 1,000 MHz
1 MHz = 0.001 GHz
| Gigahertz [GHz] | Megahertz [MHz] |
|---|---|
| 0.01 GHz | 10 MHz |
| 0.1 GHz | 100 MHz |
| 1 GHz | 1,000 MHz |
| 2 GHz | 2,000 MHz |
| 5 GHz | 5,000 MHz |
| 10 GHz | 10,000 MHz |
| 20 GHz | 20,000 MHz |
| 50 GHz | 50,000 MHz |
| 100 GHz | 100,000 MHz |
One gigahertz equals exactly 1000 megahertz.
5.8 GHz equals 5800 MHz.
MHz is clearer when matching radio tables, channel plans, or hardware references that list frequencies in millions of hertz.
