Resistance of traces | 14 September, 1999

I am looking to find a formula to calculate the resistance of circuit traces based on width

| I am looking to find a formula to calculate the resistance of circuit traces based on width | The old MIL-STD-275 became IPC-STD-275 became IPC-2221/2222. Anyway, they had/have simple graphic representations converting AWG standards into equivalent trace width/thicknesses as circular mils for power conversions and, therefore, resistance. For impedance, see my article in SMTexpress in the next few days.
