Microohm Metre (µΩ·m)
The microohm metre is 10⁻⁶ Ω·m. It is numerically equal to Ω·mm²/m; heating alloys such as nichrome are about 1.1 µΩ·m.
Symbol: µΩ·m (ASCII: uohm*m)
Quantity: electrical resistivity
SI relation: 1 µΩ·m = 0.000001 Ω·m (exact)
Derivation: 1 µΩ·m = 10⁻⁶ Ω·m = 1 Ω·mm²/m
Exact: yes, by definition
Same quantity as ohm square millimetre per metre (Ω·mm²/m) : the factor between them is exactly 1.
Typical uses
- Resistance and heating alloys
- Stainless and electrical steels
