AWG 14 Wire
Diameter 0.0641″
Millimeters 1.628 mm
Cross-section 4,109 cmil
mm² 2.08
Nominal bare-conductor dimensions per ASTM B258. AWG is geometric: d = 0.005 × 92(36−n)/39 in with n = 14; area is derived from the diameter. Ampacity depends on insulation, bundling, and the electrical code in force — it is a property of the installation, not the gauge.
