There are `2pi` radians in `360^@` . (Imagine a circle of radius 1. The circumference is `pi*d=2pi` -- but radian measure is the distance around the circle.) Then there are `pi` radians in `180^@` .

`pi"radians"=180^@` ``Divide both sides by `pi` :

1 rad = `180^@/pi`   Multiply both sides by `(-5pi)/6` :
