## How to Convert Revolutions Per Minute to Radians Per Second

To convert a revolution per minute measurement to a radian per second measurement, multiply the frequency by the conversion ratio.

Since one revolution per minute is equal to 0.10472 radians per second, you can use this simple formula to convert:

The frequency in radians per second is equal to the revolutions per minute multiplied by 0.10472.

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

The following formula can also be used to convert the frequency in revolutions per minute to angular frequency in radians per second:

Thus, the angular frequency in radians per second is equal to the frequency in revolutions per minute divided by 60 times 2 times pi.

**For example,**here's how to convert 5 RPM to rad/s using this formula.

rad/s = 0.083333 × 2π

rad/s = 0.523599

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

## Revolutions Per Minute

Revolutions per minute are a measure of the number of turns, or revolutions, that occur per 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 = RevolutionsTime_{m}

## Radians Per Second

Radians per second are a measure of angular frequency, or rotational speed, equal to the change in orientation or angle of an object in radians per second.

Radians per second can be abbreviated as *rad/s*; for example, 1 radian per second can be written as 1 rad/s.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^{[1]}
