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 circular mil per foot
The ohm circular mil per foot (Ω·cmil/ft) is the US customary resistivity unit for wires and cables, equal to π×6.4516×10⁻¹⁰/(4×0.3048) Ω·m ≈ 1.66243×10⁻⁹ Ω·m. Copper has resistivity ≈1.012 Ω·cmil/ft; wire tables in NFPA 70 (NEC) and ASTM B3 list conductor resistivity in this unit. 1 Ω·cmil/ft ≈ 1.66243 nΩ·m.
