## #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:

**A _{n}_{ (kcmil)} = 1000×d_{n}^{2} = 1000×(0.2576 in)^{2} = 66.3713 kcmil**

### If you need to find 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}**

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

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

## #2 AWG wire diameter

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

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

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

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

## #2 AWG resistance

Calculate #2AWG Resistance using the table provided below!

Nichrome | 9.9694 | 1.1×10^{-6} | 32.7081 |

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

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

### 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 25.4^{2} times the cross sectional area *A _{n}* measured in 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

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

^{2}):

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