Hertz to Rpm
The hertz is the SI unit of frequency, one cycle per second, used for sound pitch, electrical current, and CPU clock speed. Revolutions per minute measures rotational speed, used to describe engine, hard drive, and turntable speeds. 1 Hz equals 60 rpm, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to frequency, measured here against frequency's base unit (Hz) — every other frequency unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
rpm = Hz × 60
Hz = rpm × ≈0.0166667
Worked example: 5 Hz × 60 = 300 rpm.

Frequently asked
- How many RPM in a hertz?
- 1 Hz equals 60 rpm.
- How do I convert Hertz to RPM?
- Multiply the value in Hz by 60 to get rpm. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Hertz and RPM are both defined by a fixed conversion factor to frequency's base unit (Hz), so the result shown is exact to the precision displayed, not an approximation.
