Electric resistivity (symbol: ρ) is the inverse of electric conductivity, and so is formally electic field strength divided by electric current density. It is more usually described by reference to the electric resistance of a metal wire: the resistivity is the resistance of a wire multiplied by its cross-sectional area divided by its length. Electric resistivity is measured in ohm metres (Ω m) or, more usually, in the CGS unit of ohm centimetres (Ω cm): 1 Ω m = 100 Ω cm.
