RPM to BPM Conversion Table
Common values, ready to copy:
| RPM | BPM |
|---|---|
| 1 RPM | 1 BPM |
| 2 RPM | 2 BPM |
| 5 RPM | 5 BPM |
| 10 RPM | 10 BPM |
| 25 RPM | 25 BPM |
| 50 RPM | 50 BPM |
| 100 RPM | 100 BPM |
| 1,000 RPM | 1000 BPM |
Formula
BPM = RPM × 1
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 RPM and BPM
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).
BPM (BPM): Beats per minute; the standard tempo unit in music, mathematically identical to RPM. Common uses: Music tempo (a typical pop song is 100-140 BPM), heart rate (a healthy adult resting pulse is 60-100 BPM), and exercise tracking.
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 BPM = RPM × 1, 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 RPM and BPM 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.
