๐ AWG Wire Gauge Converter
Diameter (mm)0.8118
Diameter (inch)0.03196
Area (mmยฒ)0.5176
Area (kcmil)1
Convert an American Wire Gauge (AWG) number into wire diameter (mm/inch) and cross-sectional area (mmยฒ/kcmil), or find the nearest AWG number for a given diameter. Calculations use the standard AWG exponential formula.
How to use
- Choose "AWG to diameter" or "diameter to AWG" mode.
- Enter the AWG number or diameter (mm).
- The diameter/area, or nearest AWG number, is calculated automatically.
FAQ
What is AWG?
American Wire Gauge is a standardized wire size system widely used in North America. A smaller number means a thicker wire.
What formula is used?
The standard exponential formula d(n) = 0.005in ร 92^((36-n)/39), which defines wire diameter relative to AWG 36 as the reference point.
Does this calculate current-carrying capacity (ampacity)?
No, this tool only converts geometric properties (diameter and area). Ampacity depends heavily on insulation and installation conditions, so itโs out of scope.
