%IACS to Microsiemens per Centimetre (%IACS to µS/cm)
1 percent IACS (%IACS) = 5800000000 microsiemens per centimetre (µS/cm). 1 µS/cm = 1.724137931 × 10⁻¹⁰ %IACS. Example: 15 %IACS = 15 × 5800000000 = 87000000000 µS/cm.

How to Convert %IACS to Microsiemens per Centimetre
- 1 %IACS = 5800000000 µS/cm
- 1 µS/cm = 1.724137931 × 10⁻¹⁰ %IACS
- Example: convert 15 %IACS to µS/cm: 15 %IACS = 15 × 5800000000 µS/cm = 87000000000 µS/cm
Reference conditions. %IACS: 100 %IACS = 58 MS/m at 20 °C (International Annealed Copper Standard)
Formula
µS/cm = %IACS × 5800000000
Derivation from SI units:
- 100 %IACS = 58 m/(Ω·mm²) = 58 MS/m at 20 °C, so 1 %IACS = 0.58 MS/m (exact)
- 1 µS/cm = 10⁻⁴ S/m = 0.001 mS/cm
- 1 %IACS = 580000 S/m ÷ 0.0001 S/m per µS/cm = 5800000000 µS/cm
Both units are defined exactly, so the factor is exact. %IACS definition: percent IACS; Microsiemens per Centimetre definition: microsiemens per centimetre.
Worked examples
- A reading of 45 %IACS converts to 261000000000 µS/cm.
45 %IACS × 5800000000 = 261000000000 µS/cm - A value of 100 %IACS is 580000000000 µS/cm.
100 %IACS × 5800000000 = 580000000000 µS/cm

Where it's used
%IACS are used for copper and aluminium conductor grading, while microsiemens per centimetre appear in drinking, boiler and cooling water quality. Both measure electrical conductivity, so the conversion is a fixed factor.
