About electric resistivity units
Resistivity is a material property: the resistance of a unit cube. Copper is about 1.68 × 10⁻⁸ Ω·m (1.68 µΩ·cm); US wire tables use ohm-circular-mils per foot.

Frequently asked questions
What is the SI unit of electric resistivity?
This converter uses the ohm meter (Ω⋅m) as its reference unit; every other unit is defined relative to it.
How many electric resistivity units can I convert?
7 units are supported here, across SI, Metric, US customary, CGS systems. Every pair can be converted in both directions.
Does this electric resistivity converter work offline?
