Convert Revolutions per Second to Hertz (rps to Hz)
1 revolution per second (rps) = 1 hertz (Hz). 1 Hz = 1 rps. Example: 15 rps = 15 × 1 = 15 Hz.
Also searched as revolutions per second to Hz, revolutions per second in Hz, revolutions per second into hertz, rps to Hz, rps in hertz, rps into hertz, revolution per second to hertz, rps to hertz converter and how many hertz in a revolution per second.

How to Convert Revolution per Second to Hertz
- 1 rps = 1 Hz
- 1 Hz = 1 rps
- Example: convert 15 rps to Hz: 15 rps = 15 × 1 Hz = 15 Hz
Formula
Hz = rps × 1
Derivation from SI units:
- 1 rev/s = 1 Hz.
- 1 Hz = 1 s⁻¹, one cycle per second.
Both units are defined exactly, so the factor is exact. Revolution per Second definition: revolution per second; Hertz definition: hertz.
Worked examples
- A reading of 10 rps converts to 10 Hz.
10 rps × 1 = 10 Hz - A value of 100 rps is 100 Hz.
100 rps × 1 = 100 Hz
Revolution per Second to Hertz conversion table
| Revolutions per Second (rps) | Hertz (Hz) |
|---|---|
| 1 rps | 1 Hz |
| 5 rps | 5 Hz |
| 10 rps | 10 Hz |
| 25 rps | 25 Hz |

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

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