3 terminology and units of measurement

3.1 International Annealed Copper Standard (IACS) When the temperature is 20 ℃, when a uniform cross-section S of 1mm2, 1m length of copper wire has a resistance R (1/58) when Ω, defined as 100% IACS, is calculated as equation (1). σ = ·1 (1) Where. --- conductivity [sigma], S/m; ρ --- resistivity, Ω · m; S --- copper cross-section, mm2; R --- Resistance, Ω. Therefore, by definition 100% IACS = 1m 1mm2 · 1 (1/58) Ω = 58m / (Ω · mm2) = 58MS/m The 1MS/m = 58% IACS≈1.72413% IACS ......
