How to Convert Revolutions per Minute to Hertz

Reviewed by

To convert a measurement in revolutions per minute to a measurement in hertz, divide the frequency by the following conversion ratio: 60 revolutions per minute/hertz.

Since one hertz is equal to 60 revolutions per minute, you can use this simple formula to convert:

hertz = revolutions per minute ÷ 60

The frequency in hertz is equal to the frequency in revolutions per minute divided by 60.

For example, here's how to convert 5 revolutions per minute to hertz using the formula above.

hertz = (5 RPM ÷ 60) = 0.083333 Hz

Revolutions per minute and hertz are both units used to measure frequency. Keep reading to learn more about each unit of measure.

What Are Revolutions per Minute?

Revolutions per minute are a measure of the number of rotations, turns, or revolutions, that an object makes each minute.

Revolutions per minute can be abbreviated as RPM, and are also sometimes abbreviated as rev/min or r/min. For example, 1 revolution per minute can be written as 1 RPM, 1 rev/min, or 1 r/min.

Revolutions per minute can be expressed using the formula:

RPM = Revolutions / Time in Minutes

What Is a Hertz?

One hertz is formally defined as the frequency of one cycle per second.^[1]

The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as Hz; for example, 1 hertz can be written as 1 Hz.

Frequency in hertz can be expressed using the formula:

Hz = Cycles / Time in Seconds
