Megahertz to RPM Conversion Table
Common values, ready to copy:
| megahertz | RPM |
|---|---|
| 1 MHz | 6.0000e+7 RPM |
| 2 MHz | 1.2000e+8 RPM |
| 5 MHz | 3.0000e+8 RPM |
| 10 MHz | 6.0000e+8 RPM |
| 25 MHz | 1.5000e+9 RPM |
| 50 MHz | 3.0000e+9 RPM |
| 100 MHz | 6.0000e+9 RPM |
| 1,000 MHz | 6.0000e+10 RPM |
Formula
RPM = megahertz × 60000000
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 RPM
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.
RPM (RPM): Revolutions per minute; a practical unit for rotating machinery, equal to 1/60 Hz when reinterpreted as cycles per second. Common uses: Engine speed (idle ≈ 600-800 RPM, redline 6,000-8,000 RPM in cars), hard drive speeds (5,400 or 7,200 RPM), kitchen mixers, and turntable speeds (33⅓ or 45 RPM).
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 RPM = megahertz × 60000000, 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 RPM 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.
