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

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
