# Trace width calculator for any material

I'd really like to make a calculator which outputs the width of a conductor given the following inputs: resistivity, trace thickness, trace length, applied power (or current and voltage), not to exceed dT of 10C.

Or in other words, I'd really like a trace width calculator which could be used for any material, not just copper, at any thickness (not just 1/2oz, 1oz, etc).

Any idea on which equation(s) to use?
