How to Convert Revolutions to Circles Using an Easy Conversion Formula

Protractors are often used to measure angle
Convert revolutions to circles with this simple formula:
circles = revolutions × 1

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

For example:
5r = (5 × 1) = 5cir

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

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