How to convert degrees to radian

Conversion of degrees to radians uses the angular formula:

$$ \mbox{ Rad} = \mbox{ Deg} * \pi / 180 $$

To remember it, keep in mind that the Radians measure a circle over $ 2 \pi $ while the Degrees measure a circle over $ 360 ° $. The relationship between the two angles is $ \frac{2\pi}{360}=\frac{\pi}{180} $.

Conversion of gradians to degrees uses the formula:

$$ Deg = Grad / 400 * 360 $$
