How to Convert Radians to Gradians

Protractors are often used to measure angle

Convert radians to gradians with this simple formula:

gradians = radians × 63.661977

Converting a radian angle measurement to a gradian measurement involves multiplying the angle by the conversion ratio to find the result. One radian is equal to 63.661977 gradians, so to convert simply multiply by 63.661977.

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

Radians and gradians are both units used to measure angle. Learn more about angle and find more angle measurement conversion calculators. Radians are an angle measurement and can be abbreviated as rad, for example 1 rad. Gradians are 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.
