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?
1 revolution per minute (RPM) = 0.01666666667 hertz (Hz).
What is the formula to convert revolutions per minute to hertz?
hertz = revolutions per minute × 0.01666666667 — multiply the revolution per minute value by 0.0166667.
How do I convert RPM to Hz without a calculator?
Multiply by 0.0167 for a close estimate. Exact factor: 1 RPM = 0.01666666667 Hz.
Is this RPM-to-Hz converter accurate and private?
Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser — your input is never sent to a server, and the page keeps working offline.
