Directional Angle Display and Calculation
Shows the direction of a given angle. Angles can be entered and calculated in degrees, rad and π. Please adjust the angle with a controller or enter a value and press Show direction and convert. The other values will be calculated and the change of direction is marked with the arrow. Values between -360° and 360° can be processed, which is a full turn left or right.
If the arrow doesn't rotate, you probably use an old browser which isn't capable to do this.
