Chemical conductivity units
WebConductivity of Water. The conductivity of a solution is a measure of its ability to conduct electricity, sound, and transmit heat. The units of conductivity of water are Siemens per meter in SI and milliohms per centimetre in CGS. The symbol of … WebWater conductivity. Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10 x 10 -6 W -1 *m -1 (20 dS/m). Because the electrical current is transported by the ions in solution, the conductivity increases as the concentration of ions increases.
