The unit of measurement for electrical conductivity is commonly used as one millionth of a Siemens per centimeter (micro-siemens per centimeter or µS/cm). When measuring more concentrated solutions, the units are expressed as milli-siemens/cm (mS/cm). For ease of expression, 1000 µS/cm are equal to 1
