How to Convert Megasiemens per Metre to %IACS
- 1 MS/m = 1.724137931 %IACS
- 1 %IACS = 0.58 MS/m
- Example: convert 35 MS/m to %IACS: 35 MS/m = 35 × 1.724137931 %IACS = 60.34482759 %IACS
Reference conditions. %IACS: 100 %IACS = 58 MS/m at 20 °C (International Annealed Copper Standard)
Formula
%IACS = MS/m × 1.724137931034
Derivation from SI units:
- 1 MS/m = 10⁶ S/m = 1 m/(Ω·mm²)
- 100 %IACS = 58 m/(Ω·mm²) = 58 MS/m at 20 °C, so 1 %IACS = 0.58 MS/m (exact)
- 1 MS/m = 1000000 S/m ÷ 580000 S/m per %IACS = 1.724137931034 %IACS
Both units are defined exactly, so the factor is exact. Megasiemens per Metre definition: megasiemens per metre; %IACS definition: percent IACS.
Worked examples
- Aluminium at 35 MS/m is 60.34482759 %IACS.
35 MS/m × 1.724137931 = 60.34482759 %IACS - Brass at about 17 MS/m is 29.31034483 %IACS.
17 MS/m × 1.724137931 = 29.31034483 %IACS
