Convert Microohm-metres to Ohm-metres
Convert Microohm-metres (µΩ·m) to Ohm-metres (Ω·m) instantly and accurately.
Conversion Formula
Ω·m = µΩ·m × 1.000000000e-6
About Microohm-metres
The microohm-metre (µΩ·m) equals 10⁻⁶ Ω·m and is numerically identical to 1 Ω·mm²/m used in the cable industry. Nichrome resistance wire has resistivity ≈1.0-1.1 µΩ·m; stainless steel is 0.69-0.72 µΩ·m; manganin alloy (for precision shunts) is about 0.48 µΩ·m. 1 µΩ·m = 10⁻⁶ Ω·m = 1 Ω·mm²/m.
About Ohm-metres
The ohm-metre (Ω·m) is the SI coherent unit of electrical resistivity, equal to 1 V·m/A = 1 kg·m³·A⁻²·s⁻³. Seawater is ≈0.2 Ω·m; deionised water is ~18 MΩ·cm = 180 kΩ·m; silicon carbide ≈0.1-10 Ω·m; IEC 60287 specifies cable insulation resistivity in Ω·m. 1 Ω·m = 10² Ω·cm = 10⁶ µΩ·m.
