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.
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).
How many gradian are in a radian?
There are 63.662 gradian in 1 radian.
