Convert circles to revolutions with this simple formula:

revolutions = circles × 1

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

For example:

5cir = (5 × 1) = 5r

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

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