Thus 2 radians equals 360 degrees. This means that 1 radian = 180/ degrees, and 1 degree = /180 radians. The reason for this is that so many formulas become much easier to write and to understand when radians are used to measure angles. A very good example is provided by the formula for the length of a circular arc.
The video below is an animation of 1 radian. Notice how the length of 1 radius stretches out to a portion of the circle. That portion is 1 radian of the circle. There is a simple formula to convert radians to degrees.1Ï radian = 180. Therefore you can easily convert from one unit of measure to the other.he video below is an animation of 1 radian.
