Ohm centimeter quick reference
| Ohm centimeter | Ohm meter | Microohm centimeter | Ohm square millimeter per meter |
|---|---|---|---|
| 1 Ω·cm | = 0.01 Ω·m | = 1000000 µΩ·cm | = 10000 Ω·mm²/m |
| 10 Ω·cm | = 0.1 Ω·m | = 10000000 µΩ·cm | = 100000 Ω·mm²/m |
| 100 Ω·cm | = 1 Ω·m | = 100000000 µΩ·cm | = 1000000 Ω·mm²/m |
| 1000 Ω·cm | = 10 Ω·m | = 1000000000 µΩ·cm | = 10000000 Ω·mm²/m |
Where the ohm-centimeter fits
The next smaller electric resistivity unit is the ohm square millimeter per meter (Ω·mm²/m). 1 Ω·cm = 10000 Ω·mm²/m, and 1 Ω·mm²/m = 0.0001 Ω·cm.
The next larger electric resistivity unit is the ohm-meter (Ω·m). 1 Ω·cm = 0.01 Ω·m, and 1 Ω·m = 100 Ω·cm.
