A. Ohm B. Watt C. mho D. None of these Conductivity is usually measured in micro- or millisiemens per centimeter (uS/cm or mS/cm). It can also be reported in micromhos or millimhos/centimeter (umhos/cm or mmhos/cm), though these units are less common. One siemen is equal to one mho 1. Conductivity is usually measured in micro- … Read more
