Learn How to Convert Circles to Grad Using our Conversion Formula

Converting a circle angle measurement to a grad measurement involves multiplying your angle by the conversion ratio to find the result. A circle is equal to 400 grad, so to convert simply multiply by 400.

For example, 5cir = (5 × 400) = 2,000^g.

Circles and grad 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 grad is an angle measurement and can be abbreviated as ^g, for example 1^g.

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 100grad.
