AWG Converter

About This Tool

This AWG converter translates American Wire Gauge values into usable physical and electrical wire properties. It targets electrical engineers, technicians, students, and procurement staff who need reliable wire sizing data for copper conductors. The tool computes diameter in millimeters and inches, cross-sectional area in square millimeters, and circular mils, then estimates copper resistance per unit length at a reference temperature. Conceptually, the calculation follows the standard AWG relationship for diameter, then derives area and resistance from basic geometry and material properties. The value is applicable in design reviews, documentation, and supplier validation, facilitating consistent comparisons across gauges. Unique value lies in combining geometric and electrical outputs in a single, repeatable calculation with clear default assumptions (copper, 20 C) and optional material or temperature adjustments for advanced use cases. Use cases include selecting conductor size for a given current, estimating voltage drop, and preparing procurement data sheets. Core features include automatic diameter conversion, area and CM calculation, and copper resistance estimation. Advanced users can switch material to aluminum, adjust temperature, or request long-form resistance outputs for length-based calculations. The tool’s outputs support both imperial and metric reporting requirements, enabling straightforward integration into technical documents and BOMs.
