Results may differ while dealing with real wires: as it depends on the resistance of the material used and also on the number of strands in wire.

Wire’s resistance per foot

Assume the n gauge wire resistance R measured in ohms per kilofeet (Ω/kft) can easily be calculated as it equal to 0.3048×1000000000 times the resistance of the wire ρ in ohm-meters (Ω·m) and it is divided by 25.42 times the cross sectional area An in the square inches (in2):

Rn (Ω/kft) = 0.3048 × 109 × ρ(Ω·m) / (25.42 × An (in2))

Resistance per meter

Let’s Calculate the n number of gauge wire resistance R measured in ohms per kilometer (Ω/km) can easily be calculated as it is equal to 1000000000 times the resistance of the wire ρ in ohm-meters (Ω·m) and it divided by the cross sectional area Awhich is measured in square millimeters (mm2):

Rn (Ω/km) = 109 × ρ(Ω·m) / An (mm2)

#2 AWG wire area

The area of #2 AWG wire can be calculated with this easy formula in kilo-circular mils:

An (kcmil) = 1000×dn2 = 1000×(0.2576 in)2 = 66.3713 kcmil

The area of #2 AWG wire in square inches:

Use this formula to calculate the area of #2 AWG wire in square inches:

A2(inch2) = (π/4)×dn2 = (π/4)×(0.2576 in)2 = 0.0521 inch2

The area of #2 AWG wire in square millimeters:

Use this simple formula to measure the area of #2AWG wire in square millimeters:

A2(mm2) = (π/4)×dn2 = (π/4)×(6.5437 mm)2 = 33.6308 mm2
