A megahertz is a frequency unit equal to one million hertz.
Megahertz became common as electronics and radio systems moved into million-cycle operating ranges.
MHz is used for radio bands, oscillators, microcontrollers, communication systems, processor clocks, and electronic test equipment.
A gigahertz is a frequency unit equal to one billion hertz.
Gigahertz became common as microwave communication, radar, and computing frequencies reached billion-cycle scales.
GHz is used for wireless bands, microwave systems, radar, satellite links, processor clocks, and high-frequency electronics.
Mathematically, gigahertz (GHz) = megahertz (MHz) converted with the formula below.
1 MHz = 0.001 GHz
1 GHz = 1,000 MHz
Formula: value × 0.001
Example: 15 MHz = 0.015 GHz
Precision note: Use the exact relationship 1000 MHz = 1 GHz. Do not over-round channel, carrier, or clock frequencies where small differences matter.
1 MHz = 0.001 GHz
1 GHz = 1,000 MHz
| Megahertz [MHz] | Gigahertz [GHz] |
|---|---|
| 0.01 MHz | 0.00001 GHz |
| 0.1 MHz | 0.0001 GHz |
| 1 MHz | 0.001 GHz |
| 2 MHz | 0.002 GHz |
| 5 MHz | 0.005 GHz |
| 10 MHz | 0.01 GHz |
| 20 MHz | 0.02 GHz |
| 50 MHz | 0.05 GHz |
| 100 MHz | 0.1 GHz |
One megahertz equals 0.001 gigahertz.
2400 MHz equals 2.4 GHz.
GHz is clearer for frequencies in the thousands of MHz, especially wireless, microwave, radar, and processor-clock values.
