30 deg = 0.5236 radians, approx.
A radian is 180/pi degrees, or about 57 degrees
One radian is about 57.3 degrees
A radian is exactly 180 / pi degrees, approximately 57.30 degrees.
A radian is an arc of the circumference of a circle and it is about 57.3 degrees.
One radian = 180/pi or about 57.3 degrees (pi = about 3.14).
For every 360 degrees, there are 2 pi radians. Therefore, there are about 57.2958 degrees for every radian.
radian = 180/2pi degrees
Degrees* pi /180
1 radian = 360/tau (or 180/pi) degrees.
-120 degrees = ~-2.0944 radians
