RE: Thickness of various Cu weight on PCBs

One ounce copper means that one square foot of a given thickness of copper will weigh one ounce.  Now if you look up the volumetric weight of copper and work backwards, you will find that one ounce of copper in a sheet one foot square is about 0.00135 inches thick.

The proof is left to the student.

Check the webside of Rogers.
