WebThe IACS is an annealed copper standard held at 20°C with an accepted conductivity value of 58×10⁶ S/m [1.72 µΩ-cm]. Therefore, a reported conductivity of 50% IACS implies that the material has half of the conductivity of an annealed copper standard, or 27.5 x10⁶ S/m [3.45 µΩ-cm]. Silver, copper, and gold are reported as having the ... WebAug 14, 2003 · the resistance per 1000 feet of annealed copper wire at 20degrees C for AWG gauge numbers amazingly closely from the very simple formula, 10^(0.1*AWG-1), so for 10 gauge wire, it predicts 1 ohm, and my wire table says 0.9989 ohms and for 30 gauge it predicts 100 ohms, while the table says 103.2.
