How to Convert Millisiemens per Centimetre to %IACS
- 1 mS/cm = 1.724137931 × 10⁻⁷ %IACS
- 1 %IACS = 5800000 mS/cm
- Example: convert 15 mS/cm to %IACS: 15 mS/cm = 15 × 1.724137931 × 10⁻⁷ %IACS = 0.000002586206897 %IACS
Reference conditions. %IACS: 100 %IACS = 58 MS/m at 20 °C (International Annealed Copper Standard)
Formula
%IACS = mS/cm ÷ 5800000
Derivation from SI units:
- 1 mS/cm = 0.1 S/m = 1000 µS/cm
- 100 %IACS = 58 m/(Ω·mm²) = 58 MS/m at 20 °C, so 1 %IACS = 0.58 MS/m (exact)
- 1 mS/cm = 0.1 S/m ÷ 580000 S/m per %IACS = 1.724137931034 × 10⁻⁷ %IACS
Both units are defined exactly, so the factor is exact. Millisiemens per Centimetre definition: millisiemens per centimetre; %IACS definition: percent IACS.
Worked examples
- A reading of 1 mS/cm converts to 1.724137931 × 10⁻⁷ %IACS.
1 mS/cm × 1.724137931 × 10⁻⁷ = 1.724137931 × 10⁻⁷ %IACS - A value of 5 mS/cm is 8.620689655 × 10⁻⁷ %IACS.
5 mS/cm × 1.724137931 × 10⁻⁷ = 8.620689655 × 10⁻⁷ %IACS
