Move Robot a set angle

Hi,

In order to align my team's robot to the target, we need to move the robot a certain number of degrees.
We have 4 Motor Drive with encoders on a cimple gearbox. We have already written the code to figure out how many degrees to move, but we cannot figure out how that corresponds to wheel movement. I would assume that it is dependent on wheel size and robot size.

Wheels:

8" Diameter, 25.1327412" circumference

Robot:

I am unsure as to how wide the robot is, because I don't have it in front of me right now, but an explanation of how to use the width (If necessary) would be helpful.



My question is, How do I figure out how much to move the wheels?
