Calculation Results

Cross-sectional area: 0.00 mm²
Diameter: 0.00 mm
Wire weight per unit length: 0.00 g/m

Calculation Formula

Area (mm²) = π × (diameter/2)²

Where:
π = 3.14159
diameter = 0.127 mm × 92^(36-gauge) / (39 + gauge)
Area = Cross-sectional area in square millimeters

Understanding AWG

American Wire Gauge (AWG) is a standard system for classifying the diameter of round, solid, nonferrous, electrically conducting wire. A lower AWG number indicates a larger diameter and greater cross-sectional area, allowing for higher current-carrying capacity.

When to Use This Calculator

  • Electrical engineers designing circuits
  • Technicians selecting appropriate wire sizes
  • DIY enthusiasts working on electrical projects
  • When selecting wire for specific voltage drop requirements

Example Application

For example, AWG 12 wire has a cross-sectional area of approximately 6.3 square millimeters, making it suitable for most household electrical applications requiring up to 20-30 Amps.
