Gradian to Radian Converter

Gradian

In trigonometry, the gradian, also known as the gon, grad, or grade, is a unit of measurement of an angle, defined as one hundredth of the right angle. Therefore, there are 100 gradians in 90 degrees. It is equivalent to 1/400 of a turn, 9/10 of a degree, or π/200 of a radian. Gradians are primarily used in surveying, mining and geology.

Radian

The radian, (symbol: rad), is the SI unit of angle, and is the standard unit of angular measure. One radian is defined as the angle subtended from the center of a circle which intercepts an arc equal in length to the radius of the circle. A right angle is exactly π/2 radians. 2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π degrees (approximately 57.295779513082320876 degrees).
