Convert Revolutions per Second to Kilohertz (rps to kHz)
1 revolution per second (rps) = 0.001 kilohertz (kHz). 1 kHz = 1000 rps. Example: 15 rps = 15 × 0.001 = 0.015 kHz.

How to Convert Revolution per Second to Kilohertz
- 1 rps = 0.001 kHz
- 1 kHz = 1000 rps
- Example: convert 15 rps to kHz: 15 rps = 15 × 0.001 kHz = 0.015 kHz
Formula
kHz = rps ÷ 1000
Derivation from SI units:
- 1 rev/s = 1 Hz.
- 1 kHz = 10³ Hz.
- 1 rps = 1 Hz ÷ 1000 Hz per kHz = 0.001 kHz
Both units are defined exactly, so the factor is exact. Revolution per Second definition: revolution per second; Kilohertz definition: kilohertz.
Worked examples
- A reading of 10 rps converts to 0.01 kHz.
10 rps × 0.001 = 0.01 kHz - A value of 100 rps is 0.1 kHz.
100 rps × 0.001 = 0.1 kHz

Where it's used
Revolutions per Second are used for turbines and centrifuges, while kilohertz appear in audio sample rates. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many kilohertz are in 1 revolution per second?
1 rps = 0.001 kHz.
How do I convert revolutions per second to kilohertz?
Multiply the value in rps by 0.001, or divide it by 1000. For example, 15 rps × 0.001 = 0.015 kHz.
Is the rps to kHz conversion exact?
Yes. Both units are defined exactly, and 1 rps is exactly 0.001 kHz.
