Electrical conductivityUnits Type ⤴

Electrical conductivity or specific conductance is the reciprocal of electrical resistivity, and measures a material's ability to conduct an electric current. It is commonly represented by the Greek letter ? (sigma), but ? (kappa) (especially in electrical engineering) or ? (gamma) are also occasionally used. Its SI unit is siemens per metre (S/m) and CGSE unit is reciprocal second (s?1). [Wikipedia: https://en.wikipedia.org/wiki/Electrical_resistivity_and_conductivity]
