This Wire Gauge Converter is a web-based tool that converts between American Wire Gauge (AWG) and
metric (mm²) wire sizes. It helps users quickly determine equivalent wire diameters, cross-sectional areas,
and current-carrying capacities based on standard wire gauge tables.
How to Use
- Enter a wire size in AWG (e.g., 14) or mm² (e.g., 2.5).
- Select conversion direction (AWG → mm² or mm² → AWG).
- Click "Convert" to see results.
- Click "Reset" to clear inputs.
Uses
This tool is essential for:
- Electricians & Engineers – Selecting correct wire sizes for installations.
- DIY Enthusiasts – Wiring projects at home (e.g., automotive, solar panels).
- Students – Learning about wire gauge standards.
- Manufacturers – Ensuring compliance with electrical codes.
Examples
Example 1: AWG to mm²
- Input: 12 AWG
- Output: Diameter: 2.05 mm
- Cross-Sectional Area: 3.31 mm²
- Estimated Ampacity: 20-25 A
Example 2: mm² to AWG
- Input: 6 mm²
- Output: Closest AWG: 10 AWG
- Diameter: 2.59 mm
- Estimated Ampacity: 30-35 A
Example 3: Error Handling
- Input: Invalid Gauge (e.g., "50 AWG")
- Output: *"Invalid input. Enter AWG (0-40) or mm² (0.05-107)."*
