How to Convert Radians to Grad Using an Easy Conversion Formula

Protractors are often used to measure angle

Convert radians to grad with this simple formula:

grad = radians × 63.661977

Converting a radian angle measurement to a grad measurement involves multiplying your angle by the conversion ratio to find the result. A radian is equal to 63.661977 grad, so to convert simply multiply by 63.661977.

For example:
5 rad = (5 × 63.661977) = 318.309886g

Radians and grad are both units used to measure angle. Learn more about angle and find more angle measurement conversion calculators. A radian is an angle measurement and can be abbreviated as rad, for example 1 rad. A grad is an angle measurement and can be abbreviated as g, for example 1g.

A radian is the measurement of the angle from the start to the end of an arc equal to the radius of the circle. 1 radian is equal to 180/π, or about 57.29578°. There are about 6.28318 radians in a circle. The radian is the standard SI unit of measurement for an angle.

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.
