Value in radian = 213.8 × 0.017453292519943 = 3.73151 radians
Definition of Degree
1 degree of arc is defined as 1/360 of a revolution. In SI units 1° is π/180 radians.
Definition of Radian
Radian describes the plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc. One radian is the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle
