13 degrees equals 0.226893 radian

All In One Units Converter



























To calculate a degree value to the corresponding value in radian, just multiply the quantity in degree by 0.017453292519943 (the conversion factor). Here is the formula:

Value in radians = value in degree × 0.017453292519943

Suppose you want to convert 13 degree into radians. Using the conversion formula above, you will get:

Value in radian = 13 × 0.017453292519943 = 0.226893 radian

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
