Convert Kilohertz to RPM (kHz to rpm)
1 kilohertz (kHz) = 60000 revolutions per minute (rpm). 1 rpm = 0.00001666666667 kHz. Example: 15 kHz = 15 × 60000 = 900000 rpm.

How to Convert Kilohertz to RPM
- 1 kHz = 60000 rpm
- 1 rpm = 0.00001666666667 kHz
- Example: convert 15 kHz to rpm: 15 kHz = 15 × 60000 rpm = 900000 rpm
Formula
rpm = kHz × 60000
Derivation from SI units:
- 1 kHz = 10³ Hz.
- 1 rpm = 1/60 revolution per second = 1/60 Hz.
- 1 kHz = 1000 Hz ÷ 0.01666666666667 Hz per rpm = 60000 rpm
Both units are defined exactly, so the factor is exact. Kilohertz definition: kilohertz; RPM definition: revolution per minute.
Worked examples
- A reading of 16 kHz converts to 960000 rpm.
16 kHz × 60000 = 960000 rpm - A value of 48 kHz is 2880000 rpm.
48 kHz × 60000 = 2880000 rpm

Where it's used
Kilohertz are used for audio sample rates, while revolutions per minute appear in engine and motor speeds. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many revolutions per minute are in 1 kilohertz?
1 kHz = 60000 rpm.
How do I convert kilohertz to revolutions per minute?
Multiply the value in kHz by 60000. For example, 15 kHz × 60000 = 900000 rpm.
Is the kHz to rpm conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
