You're basically trying to get from a certain unit of measurement to another. What you want to do is divide by the current unit (degrees) to get rid of it and multiply by the unit you want in order to obtain the result in that unit. Basically, you want do multiply your 225 deg by x*rad/deg, but to make sure you're getting the right amount, you must make sure that the upper part is the same as the lower one.  Usually you multiply by pi/180.
