### #2 AWG wire diameter

The diameter of #2 AWG wire can be measured in inches with the following formula:

**d _{2(inch)} = 0.005 inch × 92 ^{(36-2)/39} = 0.2576 inch**

**Diameter of #2 AWG wire in millimeters:**

The Diameter of #2AWG wire can easily be measured in Millimeters with the following formula:

**d _{2(mm)} = 0.127 mm × 92 ^{(36-2)/39} = 6.5437 mm**

9.9694 | 32.7081 |

Silver | 1.59×10^{-8} |
0.1441 | 0.4728 |

Nickel | 6.99×10^{-8} |
0.6335 | 2.0784 |

Aluminum | 2.82×10^{-8} |
0.2556 | 0.8385 |

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 25.4^{2} times the cross sectional area *A _{n}* in the square inches (in

^{2}):

**R _{n (Ω/kft)} = 0.3048 × 10^{9} × ρ_{(Ω·m)} / (25.4^{2} × A_{n}_{ (in}2_{)})**

**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 *A _{n }*which is measured in square millimeters (mm

^{2}):

**R _{n (Ω/km)} = 10^{9} × ρ_{(Ω·m)} / A_{n}_{ (mm}2_{)}**

## #2 AWG wire area

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

**A _{n}_{ (kcmil)} = 1000×d_{n}^{2} = 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:

**A _{2(inch}2_{)} = (π/4)×d_{n}^{2} = (π/4)×(0.2576 in)^{2} = 0.0521 inch^{2}**

*The area of #2 AWG wire in square millimeters:*

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

**A _{2(mm}2_{)} = (π/4)×d_{n}^{2} = (π/4)×(6.5437 mm)^{2} = 33.6308 mm^{2}**
