how to determine cable gauge
Stranded wire gauges should be measured bycalculating the equivalent cross sectional copper area. First,measure the bare diameter of a single strand and locate the circular mils value in the row that matches your measurement. Second,multiply the circular mils by the number of strands in the cable.

You can purchase a wire gauging tool at your local hardware store or home-supply store). Estimate the gauge size of the wire. Begin by eyeballing the approximate size of the wire and see which gauge holes are roughly the same size.
How do you calculate the diameter of a 36 gauge wire?
The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39: d n (in) = 0.005 in 92 (36-n)/39.
