#2 AWG wire area

You can take up these given formulas to calculate #2AWG Wire Area.

If you need to find out the area of #2 AWG wire in kilo-circular mils:

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

If you need to find the area of #2 AWG wire in square inches:

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

If you need to find the area of #2 AWG wire in square millimeters:

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

#2 AWG wire diameter

You can take the help of this formula to find the diameter of #2 AWG wire in inches:

d2(inch) = 0.005 inch × 92 (36-2)/39 = 0.2576 inch

If you need to calculate the diameter of #2 AWG wire in millimeters:

d2(mm) = 0.127 mm × 92 (36-2)/39 = 6.5437 mm

Wire’s resistance per foot

The n gauge wire with the resistance R in ohms per kilofeet (Ω/kft) is apparently equal to the product of 0.3048×1000000000 and the wire’s resistivity ρ in ohm-meters (Ω·m) which is further divided by 25.42 times the cross sectional area An measured in square inches (in2):

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

Resistance per meter

The n gauge wire with resistance R in ohms per kilometer (Ω/km) is totally equal to 1000000000 times the resistivity ρ of wire which is calculated in ohm-meters (Ω·m) and hence it is divided by the cross sectional area An measured in square millimeters (mm2):

Rn (Ω/km) = 109 × ρ(Ω·m) / An (mm2)
