About these units
Revolutions per Minute (rpm): Revolutions per minute (rpm) measures rotational speed of engines, fans, drives and turntables.
Hertz (Hz): The hertz is the SI unit of frequency: one cycle per second.
Frequently asked questions
How many hertz are in 1 revolution per minute?
1 revolution per minute (rpm) equals 0.01666666667 hertz (Hz).
How do I convert rpm to Hz?
Multiply the value in revolutions per minute by 0.01666666667. For example, 5 rpm × 0.01666666667 = 0.08333333333 Hz.
How do I convert hertz back to revolutions per minute?
Multiply by 60 (or divide by 0.01666666667). 1 Hz = 60 rpm.
What does rpm mean?
Revolutions per minute (rpm) measures rotational speed of engines, fans, drives and turntables.
