What units is conductivity expressed in?

Conductivity is a measure of a material's ability to conduct electric current, which is influenced by the presence of ions in a solution, such as those found in drinking water. The standard unit of measurement for conductivity is microohms per centimeter. This unit provides a clear and quantifiable means to assess the ability of the water to conduct electricity, which correlates with the concentration of dissolved ionic substances.

The use of microohms per centimeter is particularly relevant in the context of water quality analysis because it allows for precise measurements, crucial for monitoring drinking water standards and safety. By using this specific unit, analysts can evaluate the conductivity of water sample accurately and determine whether they meet health guidelines or require treatment. This makes it essential for laboratory analysts working with drinking water to understand and utilize this measurement effectively.
