Electrical resistivity and conductivity
Electrical conductivity (or specific conductance) is the reciprocal of electrical resistivity.It represents a material's ability to conduct electric current. It is commonly signified by the Greek letter σ (), but κ (especially in electrical engineering) [citation needed] and γ [citation needed] are sometimes used. The SI unit of electrical conductivity is siemens per metre (S/m).

Electrical Conductivity and Resistivity
The units of conductivity are sometimes given as mhos/meter or millimhos/meter. Resistivity (ρ) is the inverse of conductivity (ρ = 1 / σ). The units of resistivity are Ohm meters (Ωm). The electrical conductivity of earth materials is influenced by metal content (e.g., sulfides), porosity, clay content, permeability, and the saturation.
