The unit of measurement for conductivity is expressed in either microSiemens (uS/cm) or micromhos (umho/cm) which is the reciprocal of the unit of resistance, the ohm. The prefix micro means that it is measured in millionths of a mho. MicroSiemens and micromhos are equivalent units.
Conductivity is water's ability to allow the flow of electricity and is defined as the reciprocal of resistivity, which is water's opposition to the flow of current. Water's conductivity is directly proportional to the amount of ions in the water. The more ions in the water, the higher the level of conductivity.
