Hz to RPM Converter (with Examples and Formula)

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


Enter the Hz value below

🔁 RPM to Hz


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

RPM = 60 × Hz

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 100 Hz, use the calculator above to find the equivalent value is 6000 RPM.

For a value of 20 Hz, the equivalent rotational speed is 1200 RPM

How to calculate RPM from Hz

To calculate Revolutions per minute value from Frequency, simply multiply Hz by 60.

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.

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.
