Electric Resistivity Converter
Convert electrical resistivity (a material property describing how strongly it opposes electric current) between ohm metres and related units.

Quick answer
Resistivity is a material property (effectively the resistance of a unit cube), measured in ohm metres. One ohm centimetre is 0.01 Ω·m and one microhm centimetre is 10⁻⁸ Ω·m. Unlike resistance it does not depend on the shape of the sample, which is what makes it useful for comparing one material with another.
| Ohm metre (Ω·m) | 1 |
| Ohm centimetre (Ω·cm) | 100 |
| Ohm inch (Ω·in) | 39.37007874 |
| Microohm centimetre (µΩ·cm) | 100000000 |
About the Electric Resistivity Converter
Electrical resistivity is a material property describing how strongly it resists electric current, independent of shape. The SI unit is the ohm metre.
Low resistivity indicates a good conductor; high resistivity indicates an insulator.
Frequently Asked Questions
What is resistivity?
⌄
Resistivity is an intrinsic property of a material describing how much it resists current flow, regardless of its size or shape.
How is resistivity different from resistance?
⌄
Resistance depends on a specific object’s size and shape; resistivity is a property of the material itself.
Which materials have low resistivity?
⌄
Metals such as copper and silver have very low resistivity, making them excellent conductors.
