Formula and field context
Convert between American Wire Gauge and approximate metric conductor area for documentation and cross-reference checks.
Formula context
AWG to mm2 Chart
AWG-to-mm2 is an area cross-reference, not an ampacity approval. It helps a foreman, designer, or purchasing team translate conductor metal area between AWG and metric notation. The final U.S. installation still needs the actual conductor type, insulation, terminal rating, ampacity, and equipment listing checked separately.
Formula
Approximate area in mm2 = 0.012668 x 92^((36 - AWG) / 19.5).Variables to keep with the result
- AWG is the American Wire Gauge number.
- Area is approximate metallic conductor area, not cable outside diameter.
What the conversion means
AWG is a gauge system, while mm2 is a cross-sectional area. The conversion is useful when comparing documentation, drawings, imported equipment, and conductor references, but it does not automatically approve ampacity, insulation, terminal temperature, or wiring method.
U.S. field context
U.S. installations commonly use AWG and kcmil conductor names, while equipment documentation may show metric areas. The conversion provides a conductor-area cross-reference for plan notes, equipment nameplates, and submittals before moving into wire-size, ampacity, and voltage-drop calculations.
Common mistakes
Do not pick a conductor only because the metric area looks close. Conductor material, insulation type, terminal rating, ambient temperature, raceway fill, bundling, and voltage drop can all change the final selection. Treat the result as a conversion note, then move into the full calculator when the result affects installation.
