Calculation Formula

The cross-sectional area (A) in square millimeters is calculated using:

A = 0.012668 ${Math.pow(92/ln(10), 2)}$ / ${Math.pow((ln((outer_diameter - 2*insulation_thickness)/outer_diameter)/ln(10)), 2)}$

Where:
- A = Cross-sectional area in square millimeters
- outer_diameter = Outer diameter of the wire in millimeters
- insulation_thickness = Thickness of the insulation in millimeters
- ln = Natural logarithm

Result

0.0000 mm²

Working Principle

The American Wire Gauge (AWG) system is a standard for specifying wire diameter and cross-sectional area. AWG ratings increase as wire diameter decreases. This calculator converts AWG to square millimeters by calculating the cross-sectional area of the wire based on its diameter.

Applications

This calculator is useful for electrical engineers, electricians, and anyone working with electrical wiring. It helps in selecting the appropriate wire size for electrical applications based on AWG rating, ensuring proper current capacity and voltage drop.

Formula Explanation

The calculation uses the formula for the cross-sectional area of a wire:

A = πr²

Where r is the radius of the wire. The outer diameter is calculated based on the AWG number, and the cross-sectional area is derived from this.
