## How to Convert Circles to Revolutions

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

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

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

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

## 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.

## Revolutions

A revolution, or turn, 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, cycle, or complete rotation. Revolutions can be abbreviated as *r*, and are also sometimes abbreviated as *rev* or *cyc*. For example, 1 revolution can be written as 1 r, 1 rev, or 1 cyc.
