SI symbols follow international notation. U.S. and Imperial measures are labelled separately where their values differ.
Ohm Metre (Ω·m) and ohm square millimetre per metre (Ω·mm²/m) are units of electrical resistivity. Use this page to convert in either direction.
| Ohm Metre (Ω·m) | Ohm Square Millimetre Per Metre (Ω·mm²/m) |
|---|---|
| 1 Ω·m | 1000000 Ω·mm²/m |
| 5 Ω·m | 5000000 Ω·mm²/m |
| 10 Ω·m | 10000000 Ω·mm²/m |
| 100 Ω·m | 100000000 Ω·mm²/m |
