Megahertz to Hertz Conversion Table
Common values, ready to copy:
| megahertz | hertz |
|---|---|
| 1 MHz | 1.0000e+6 Hz |
| 2 MHz | 2.0000e+6 Hz |
| 5 MHz | 5.0000e+6 Hz |
| 10 MHz | 1.0000e+7 Hz |
| 25 MHz | 2.5000e+7 Hz |
| 50 MHz | 5.0000e+7 Hz |
| 100 MHz | 1.0000e+8 Hz |
| 1,000 MHz | 1.0000e+9 Hz |
Formula
hertz = megahertz × 1000000
Frequency uses the SI hertz (Hz, cycles per second). 1 kHz = 1,000 Hz; 1 MHz = 1 million Hz; 1 GHz = 1 billion Hz. RPM and BPM are both "cycles per minute": 60 RPM = 1 Hz.
About Megahertz and Hertz
Megahertz (MHz): A million hertz; the unit for FM radio, older computer clock speeds, and microwave-band wireless. Common uses: FM radio (88-108 MHz), microcontroller clock speeds, ham radio, and some Wi-Fi specifications.
Hertz (Hz): Cycles per second; named for Heinrich Hertz, who experimentally demonstrated electromagnetic waves in 1887. Common uses: Audio (Hz range for human hearing is 20-20,000 Hz), AC power frequency (50 or 60 Hz), and the SI base unit for any periodic phenomenon.
How the conversion works
Frequency uses the SI hertz (Hz, cycles per second). 1 kHz = 1,000 Hz; 1 MHz = 1 million Hz; 1 GHz = 1 billion Hz. RPM and BPM are both "cycles per minute": 60 RPM = 1 Hz.
The exact relationship is hertz = megahertz × 1000000, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between megahertz and hertz comes up wherever frequency measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
