Formula
Formula
rpm = Hz × 60
Multiply any value in hertz by 60 to obtain the value in revolutions per minute.
Worked example
Convert 50 Hz to rpm.
- 01Start with 50 Hz.
- 02Multiply by the conversion factor: 50 × 60 = 3000 rpm.
Result50 Hz = 3000 rpm

FAQ
What is the conversion factor from Hz to rpm?
1 Hz equals 60 rpm. To convert, multiply the value in hertz by 60.
How do I convert 1 Hz to rpm?
1 Hz = 60 rpm. For any value, multiply by 60.
How do I convert rpm back to Hz?
Divide by the same factor — or equivalently, multiply by 0.01666667. So 1 rpm = 0.0166667 Hz.
When would I need to convert hertz to revolution per minute?
Frequency conversions between Hz and rpm are needed in signal and RF engineering, motor and turbomachinery rotational-speed work, vibration and pulse-rate analysis, and control-loop sample-rate specification. Hz dominates electronics and instrumentation; kHz, MHz and GHz cover audio through microwave; rpm and rps dominate mechanical rotational equipment; cycles per minute, second and hour cover slow industrial cyclic processes. Angular frequency (rad/s) and time-period (Hz ↔ seconds) conversions are NOT included — they require either a 2π factor or a reciprocal relationship.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
