Microohm centimeter quick reference
| Microohm centimeter | Ohm meter | Ohm centimeter | Ohm square millimeter per meter |
|---|---|---|---|
| 1 µΩ·cm | = 1e-8 Ω·m | = 0.000001 Ω·cm | = 0.01 Ω·mm²/m |
| 10 µΩ·cm | = 1e-7 Ω·m | = 0.00001 Ω·cm | = 0.1 Ω·mm²/m |
| 100 µΩ·cm | = 0.000001 Ω·m | = 0.0001 Ω·cm | = 1 Ω·mm²/m |
| 1000 µΩ·cm | = 0.00001 Ω·m | = 0.001 Ω·cm | = 10 Ω·mm²/m |
Where the microohm-centimeter fits
The next smaller electric resistivity unit is the ohm circular mil per foot (Ω·cmil/ft). 1 µΩ·cm ≈ 6.015304936 Ω·cmil/ft, and 1 Ω·cmil/ft ≈ 0.1662426113 µΩ·cm.
The next larger electric resistivity unit is the ohm square millimeter per meter (Ω·mm²/m). 1 µΩ·cm = 0.01 Ω·mm²/m, and 1 Ω·mm²/m = 100 µΩ·cm.
