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.
