AWG Wire Gauge Chart

AWG to Metric Conversion
Ampacity & Current Ratings
DC Resistance & Diameter

Our AWG Wire Gauge Chart provides American and metric gauge equivalents, conductor diameters, DC resistance per foot, and ampacity ratings for copper and aluminum. Whether sizing power feeders or micro-signal conductors, this table helps you balance current capacity with harness size and weight. Download the PDF or STEP version for inclusion in your electrical schematics and BOM.
