How to Convert Circles to Revolutions
To convert a measurement in circles to a measurement in revolutions, divide the angle by the following conversion ratio: 1 circles/revolution.
Since one revolution is equal to 1 circle, you can use this simple formula to convert:
revolutions = circles ÷ 1
The angle in revolutions is equal to the angle in circles divided by 1.
For example, here's how to convert 5 circles to revolutions using the formula above.
revolutions = (5 cir ÷ 1) = 5 r
How Many Revolutions Are in a Circle?
There are 1 revolution in a circle, which is why we use this value in the formula above.
1 cir = 1 r
Circles and revolutions are both units used to measure angle. Keep reading to learn more about each unit of measure.
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.

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.
