What Are Revolutions per Minute?

Revolutions per minute are a measurement of frequency.

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

How Much Is a Revolution per Minute?

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

How to Convert Revolutions per Minute

To convert revolutions per minute to another unit of frequency, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.^[1]

You can find the conversion factors for revolutions per minute in the conversion table below.

Then, multiply the frequency measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

revolutions per minute × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
