Convert Kilohertz to Revolutions per Second (kHz to rps)
1 kilohertz (kHz) = 1000 revolutions per second (rps). 1 rps = 0.001 kHz. Example: 15 kHz = 15 × 1000 = 15000 rps.

How to Convert Kilohertz to Revolution per Second
- 1 kHz = 1000 rps
- 1 rps = 0.001 kHz
- Example: convert 15 kHz to rps: 15 kHz = 15 × 1000 rps = 15000 rps
Formula
rps = kHz × 1000
Derivation from SI units:
- 1 kHz = 10³ Hz.
- 1 rev/s = 1 Hz.
- 1 kHz = 1000 Hz ÷ 1 Hz per rps = 1000 rps
Both units are defined exactly, so the factor is exact. Kilohertz definition: kilohertz; Revolution per Second definition: revolution per second.
Worked examples
- A reading of 16 kHz converts to 16000 rps.
16 kHz × 1000 = 16000 rps - A value of 48 kHz is 48000 rps.
48 kHz × 1000 = 48000 rps

Where it's used
Kilohertz are used for audio sample rates, 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 kilohertz?
1 kHz = 1000 rps.
How do I convert kilohertz to revolutions per second?
Multiply the value in kHz by 1000. For example, 15 kHz × 1000 = 15000 rps.
Is the kHz to rps conversion exact?
Yes. Both units are defined exactly, and 1 kHz is exactly 1000 rps.
