How to Convert Grad to Radians Using an Easy Conversion Formula

Protractors are often used to measure angle

Convert grad to radians with this simple formula:

radians = grad × 0.015708

Converting a grad angle measurement to a radian measurement involves multiplying your angle by the conversion ratio to find the result. A grad is equal to 0.015708 radians, so to convert simply multiply by 0.015708.

For example:
5g = (5 × 0.015708) = 0.07854 rad

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

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.
