Do you want to convert circles to revolutions?

## How to Convert Revolutions to Circles

To convert a measurement in revolutions to a measurement in circles, divide the angle by the following conversion ratio: 1 revolutions/circle.

Since one circle is equal to 1 revolution, you can use this simple formula to convert:

circles = revolutions ÷ 1

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

For example, here's how to convert 5 revolutions to circles using the formula above.
circles = (5 r ÷ 1) = 5 cir

### How Many Circles Are in a Revolution?

There are 1 circle in a revolution, which is why we use this value in the formula above.

1 r = 1 cir

## What is a Revolution?

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.

## What is a Circle?

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.

A circle is more commonly used to describe a round, symmetrical shape with no corners or edges than it is to describe plane angle. The shape is described by its radius and circumference.
