Radians

Radians: 1 radian is the angle where the length of the arc (red)
is equal to the radius (blue) of the circle.

A full circle contains 2 π radians.

Conversion from Radians to Degrees

$degrees = \frac{radians \cdot 180}{π}$

Conversion from Degrees to Radians

$radians = \frac{degrees \cdot π}{180} document.addEventListener('DOMContentLoaded', function() {
