Radians and Degrees Conversion

The video tutorial explains how to convert radians to degrees, focusing on pi and negative pi/3 radians. It begins by establishing that one full revolution is 2 pi radians or 360 degrees. The tutorial then simplifies the conversion of pi radians to 180 degrees. Finally, it demonstrates converting negative pi/3 radians to degrees by calculating the degrees per radian and applying it to the given value, resulting in negative 60 degrees.
