FORMULA & EXAMPLES
How to convert Revolutions per minute to kilohertz
kHz = rpm ÷ 60000
Divide the rpm reading by 60000.
Worked examples
60 rpm ≈ 0.001 kHz
60 ÷ 60000 ≈ 0.001
3000 rpm ≈ 0.05 kHz
3000 ÷ 60000 ≈ 0.05
Frequently asked questions
Does rpm to hertz include a 2π factor?
No. A revolution is one full cycle, so 60 rpm is 1 Hz. Angular frequency in radians per second uses a different relationship involving 2π.
