Revolutions per minute to Hertz Converter RPM → Hz
1 revolution per minute (RPM) = 0.01666666667 hertz (Hz). Type a value below, the conversion happens instantly, entirely on your device.
1 RPM = 0.01666666667 Hz
3000 revolutions per minute = 50 hertz
3000 × 0.0166667 = 50
1 RPM equals 0.0166667 Hz, so multiplying by 0.0166667 converts the value. The result describes the exact same quantity, only the measuring stick changes.
How to convert revolutions per minute to hertz
hertz = revolutions per minute × 0.01666666667, multiply the revolution per minute value by 0.0166667.
Example: 3000 RPM = 50 Hz.
To convert the other way: revolutions per minute = hertz ÷ 0.01666666667 — or use the dedicated Hz to RPM converter .
Revolutions per minute to hertz divides by 60: a 3,000 RPM shaft turns at 50 Hz, and a 7,200 RPM drive at 120 Hz. Useful for converting a rotation speed into a frequency for vibration or balancing analysis.

About the units
What is a revolution per minute?
One revolution per minute is 1/60 Hz. Engine and motor speeds are given in RPM; 3,000 RPM is 50 Hz.
What is a hertz?
One hertz is one cycle per second, the SI unit of frequency. Mains power is 50 or 60 Hz; audible sound spans roughly 20 Hz to 20 kHz.
Frequently asked questions
How many hertz are in 1 revolution per minute?
