Convert Hertz to Revolutions per Second (Hz to rps)
1 hertz (Hz) = 1 revolution per second (rps). 1 rps = 1 Hz. Example: 15 Hz = 15 × 1 = 15 rps.

How to Convert Hertz to Revolution per Second
- 1 Hz = 1 rps
- 1 rps = 1 Hz
- Example: convert 15 Hz to rps: 15 Hz = 15 × 1 rps = 15 rps
Formula
rps = Hz × 1
Derivation from SI units:
- 1 Hz = 1 s⁻¹, one cycle per second.
- 1 rev/s = 1 Hz.
Both units are defined exactly, so the factor is exact. Hertz definition: hertz; Revolution per Second definition: revolution per second.
Worked examples
- A reading of 50 Hz converts to 50 rps.
50 Hz × 1 = 50 rps - A value of 440 Hz is 440 rps.
440 Hz × 1 = 440 rps

Where it's used
Hertz are used for mains power (50/60 Hz), while revolutions per second appear in turbines and centrifuges. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many revolutions per second are in 1 hertz?
1 Hz = 1 rps.
How do I convert hertz to revolutions per second?
Multiply the value in Hz by 1. For example, 15 Hz × 1 = 15 rps.
Is the Hz to rps conversion exact?
Yes. Both units are defined exactly, and 1 Hz is exactly 1 rps.
