AWG 33 Wire

Diameter 0.0071″
Millimeters 0.180 mm
Cross-section 50 cmil
mm² 0.0255

Nominal bare-conductor dimensions per ASTM B258. AWG is geometric: d = 0.005 × 92(36−n)/39 in with n = 33; 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.
