How to Convert Circles to Revolutions
To convert a circle measurement to a revolution measurement, divide the angle by the conversion ratio. One revolution is equal to 1 circle, so use this simple formula to convert:
The angle in revolutions is equal to the circles divided by 1.
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.
