Convert Revolutions per Hour to Kilohertz
Input the number of rph you want to convert to kilohertz.
How to Convert RPH to Kilohertz
The revolutions per hour and kilohertz are both units of frequency. 1 kilohertz equals 3599999.9971 rph. This means to convert rph to kilohertz, you divide by 3599999.9971.
Formula
Step-by-Step Example
Convert 5 RPH to kilohertz:
We need to convert rph to kilohertz
Since 1 kHz = 3599999.9971 RPH, divide by 3599999.9971
5 ÷ 3599999.9971 = 1.38888889e-6
5 RPH = 1.38888889e-6 kHz

About These Units
Revolutions per Hour (RPH)
Revolutions per hour (RPH) measures slow rotational speeds. Clock hour hands move at 1 RPH. Industrial mixers, rotisseries, and some conveyors operate in RPH range. Earth rotates once per 24 hours (approximately 0.042 RPH).
Kilohertz (kHz)
A kilohertz (kHz) equals 1,000 hertz. Kilohertz measures AM radio frequencies (530-1700 kHz), ultrasonic cleaning (20-40 kHz), and audio sample rates (44.1 kHz for CD quality). Human hearing upper limit is about 20 kHz.
