Greetings All,

I am looking for the formula to predict DC-Etch readings prior to oxide.
 I know IPC-MF-150F lists the resistivity of 1 oz. As .162
Ohm-gram/meter^2, however the only formulas I have seen for determining
the resistance of a conductor incorporate Rho (resistivity constant) as
Ohm-meter.  Any and all help is greatly appreciated.
