About This Tool
The AWG to MM Converter computes the conductor diameter in millimeters for a given AWG value using standard AWG tables without requiring manual lookup. It returns a single millimeter value with three-decimal precision, suitable for sizing and documentation. The tool applies the nominal diameter formula d_in = 0.005 × 92^((36 − n)/39) and converts to millimeters via d_mm = d_in × 25.4. For non-integer inputs, linear interpolation between neighboring gauge values is used to produce a smooth result. It assumes copper conductors and provides a nominal diameter rather than a finished product dimension. Use cases include selecting insulation thickness, connector bore sizing, and enclosure clearance checks. Outputs are deterministic and repeatable across environments, enabling reproducible BOMs and engineering notes.
How to Use
1. Provide inputs: Enter AWG gauge number (0–40).
2. The tool computes the conductor diameter in millimeters using the standard AWG formula.
3. Read the output diameter_mm with three-decimal precision.
4. For non-integer inputs, the system interpolates between adjacent values.
5. Use the result for insulation clearance, terminal bore sizing, or BOM documentation.
