    trace width

    Fill in the current of 8 amps, the maximum temperature rise, and the copper weight. Standard copper weight is 1 oz. Let's put in 8 amps, 20 degrees C, and 1 oz copper. The calculator tells us to use a trace width of 137 mils (that's 0.137") for an external trace or 356 mils for an internal trace.
