Quick Reference
ρ (rho)Electrical Resistivity (Ω·m)
σ (sigma)Electrical Conductivity (S/m)
1 S/m1 / (Ω·m)
Overview
Conductivity and resistivity are reciprocal properties of a material. Resistivity measures how much a material opposes the flow of electric current, while conductivity measures how easily it allows flow.
💡
Pro Tips
The formula is simple: ρ = 1 / σ.
The standard unit for conductivity is Siemens per meter (S/m).
The standard unit for resistivity is Ohm-meters (Ω·m).

Fun Facts
"Silver has the highest electrical conductivity of all metals."
"Pure water is actually a good insulator; it's the dissolved ions that make it conduct electricity."
"Superconductors have a resistivity of exactly zero below a certain temperature."
