High electrical conductivity refers to the ability of certain materials to conduct a large amount of electrical current. Electrical conductivity is abbreviated by the Greek letters sigma (Ï) or kappa (Îº). The SI unit of electrical conductivity is Siemens per meter (S/m).
Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m).esistivity of pure water (in MÏ-cm) as a function of temperature. The SI unit of conductivity is S /m and, unless otherwise qualified, it refers to 25 Â°C. Often encountered in industry is the traditional unit of Î¼S/cm. 10 6 Î¼S/cm = 10 3 mS/cm = 1 S/cm.
