How to determine the angle in Rotation

I am making a game of spinning wheel in unity. I am new to this. I want to know how to determine the angle traversed by the wheel for some rotations and first of all how to determine the total number of rotations. Please help me figure this out? Any suggestions are a welcome.

The rotation is stored in the rotation or eulerAngles variables of a transform object. Like: gameobject.transform.rotation or gameobject.transform.eulerAngles. For counting the rotation you will need to track these variables. E.g. a value of 360 eulerAngles may be a single rotation and 720 will be two rotations.
