RPM to Hz Converter (with Examples and Formula)

This calculator converts Revolutions Per Minute (RPM) to Hertz (Hz). RPM is a measure of the rotational speed while Hz is a unit of frequency. In this post we provide the formula, examples and definitions as well.

🔁 Hz to RPM


To convert RPM (Revolutions Per Minute) to Hz (Hertz), you can use the following formula:

Hz = RPM/60

This formula works because 1 Hz is equivalent to 1 cycle per second, and there are 60 seconds in a minute.

Example Calculation:

If you have a motor running at 1200 RPM, use the calculator above to find the equivalent value of Frequency (Hz) is 20.

For a value of 5000 RPM, the equivalent is 83.33 Hz.

How to calculate Hz from RPM

To calculate Hz value from Revolutions per minute, simply divide the RPM by 60.

What is Hz?

Hertz (Hz) is the unit of frequency in the International System of Units (SI). It measures the number of cycles per second of any periodic phenomenon, such as a wave or oscillation. Named after Heinrich Hertz, a German physicist who contributed significantly to the understanding of electromagnetic waves, Hertz is a fundamental concept in various fields, including physics, engineering, and electronics.

1 Hertz (Hz) equals 1 cycle per second. It quantifies how often an event repeats within one second.

What is RPM?

RPM (Revolutions Per Minute) is a unit of rotational speed that measures the number of full rotations completed by an object in one minute. It’s a common unit used to express the speed of rotation for various mechanical systems, such as engines, motors, turbines, and other rotating components.

1 RPM indicates that the object completes one full revolution in one minute. It describes how many times an object spins around its axis in a minute.
