How to Convert Gradians to Circles

Protractors are often used to measure angle

Convert gradians to circles with this simple formula:

circles = gradians × 0.0025

Converting a gradian angle measurement to a circle measurement involves multiplying the angle by the conversion ratio to find the result. One gradian is equal to 0.0025 circles, so to convert simply multiply by 0.0025.

For example:
5g = (5 × 0.0025) = 0.0125 cir

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

A grad, more specifically a gradian, is equal to 1/400 of a circle or 9/10°. The grad simplifies the measurements of right angles, as 90° is equal to 100 grad.
