# How to convert?

Hello everyone,

I need help with converting or changing degrees to radians in Microsoft Excel.

Currently I'm writing SIN and COS functions but the default angles are in degrees, not radians. How do I format it to radians?

You may want to check your answers because the default on my copy of Excel is in radians.

To get to radians from degrees:

$$x = \pi \frac { \Theta} {180}$$

x is the angle in radians
$\Theta$ is the angle in degrees.

As far as I can tell Excell defaults to Radians.
