Conductivity Formula
Formula for the conductivity of water is given as:
σ = 1/ρ
where,
- σ is Conductivity of Water
- ρ is Resistivity of Water

Conductivity of Water
Conductivity of water is the ability of water to conduct electricity or heat. It is measured using the symbols “s” or “k”. It is directly proportional to the number of conductive ions that are present in the water. Pure water has a very low conductivity as it doesn’t have any dissolved ions. On the other hand, natural water sources have different dissolved ions that increase their conductivity.
Let’s understand the conductivity of water in detail in this article.
