How to Convert Electric Resistivity Units
Resistivity is a material property describing how strongly it resists current, independent of shape. The SI unit is ohm metre (Ω·m); copper is about 1.72 × 10⁻⁸ Ω·m, often written as 0.0172 Ω·mm²/m.
Every unit on this page is stored as a fixed factor relative to one reference unit, the ohm metre (Ω·m). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in Ω·m.
- Divide that result by the factor of the target unit.

Frequently Asked Questions
What is the SI unit of electric resistivity?
The SI unit of electric resistivity is the ohm metre (Ω·m). Resistivity is a material property describing how strongly it resists current, independent of shape.
How do I convert Ω·mm²/m to Ω·m?
To convert ohm sq millimetre per metre (Ω·mm²/m) to ohm metre (Ω·m), multiply the value in Ω·mm²/m by 0.000001. For example, 1 Ω·mm²/m = 0.000001 Ω·m.
How do I convert Ω·cm to Ω·m?
To convert ohm centimetre (Ω·cm) to ohm metre (Ω·m), multiply the value in Ω·cm by 0.01. For example, 1 Ω·cm = 0.01 Ω·m.
How do I convert µΩ·cm to Ω·mm²/m?
To convert microhm centimetre (µΩ·cm) to ohm sq millimetre per metre (Ω·mm²/m), multiply the value in µΩ·cm by 0.01. For example, 1 µΩ·cm = 0.01 Ω·mm²/m.
