How to Convert Circles to Revolutions

Protractors are often used to measure angle

Convert circles to revolutions with this simple formula:

revolutions = circles × 1

Converting a circle angle measurement to a revolution measurement involves multiplying the angle by the conversion ratio to find the result. One circle is equal to 1 revolutions, so to convert simply multiply by 1.

For example:
5 cir = (5 × 1) = 5 r

Circles and revolutions are both units used to measure angle. Learn more about angle and find more angle measurement conversion calculators. Circles are an angle measurement and can be abbreviated as cir, for example 1 cir. Revolutions are an angle measurement and can be abbreviated as r, for example 1 r.

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