What is Gradian?
The gradian (symbol: grad), also known as gon, is a unit of measurement of an angle, equivalent to 1/400 of a full rotation.
One gradian is equal to 9/10 of a degree or $\pi/200$ radians.
Common Uses
Gradians are primarily used in surveying, particularly in some European countries, because they align well with the decimal system (e.g., a right angle is exactly 100 grads).
What is Radian?
The radian (symbol: rad) is the SI unit for measuring angles.
It is defined as the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle. One full rotation (360°) is equal to $2\pi$ radians.
Common Uses
The radian is the standard unit of angular measurement used in many areas of mathematics, physics, and engineering because of its natural mathematical properties.
