## How to Convert Revolutions to Circles

To convert a revolution measurement to a circle measurement, multiply the angle by the conversion ratio. One revolution is equal to 1 circles, so use this simple formula to convert:

The angle in circles is equal to the revolutions multiplied by 1.

**For example,**here's how to convert 5 revolutions to circles using the formula above.

Revolutions and circles are both units used to measure angle. Keep reading to learn more about each unit of measure.

## Revolutions

A revolution is equal to 1 rotation around a circle, or 360°. Revolutions are commonly used to measure the speed of rotation, for example when measuring the revolutions per minute (RPM) of a vehicle's engine.

A revolution is sometimes also referred to as a turn or cycle. Revolutions can be abbreviated as *r*, for example 1 revolution can be written as 1 r.

## Circles

A circle is the equivalent of 1 revolution around a circle, or 360°.

A circle is sometimes also referred to as a revolution. Circles can be abbreviated as *cir*, for example 1 circle can be written as 1 cir.
