→AWG wire diameters and approximate metric equivalents
Line 4:
The cross-sectional area of each gauge is an important factor for determining its current-carrying capacity and resistance. The AWG of a stranded wire is determined by the total cross-sectional area of the conductor. Because there are also small gaps between the strands, a stranded wire will be about 5% thicker than a solid wire with the same AWG.
