About Microohm-centimetres
The microohm-centimetre (µΩ·cm) equals 10⁻⁸ Ω·m = 10 nΩ·m, the traditional unit for bulk metal resistivity in materials science. Copper is 1.68 µΩ·cm; tungsten 5.6 µΩ·cm; platinum 10.6 µΩ·cm; CRC Handbook tables still list metal resistivities in µΩ·cm. 1 µΩ·cm = 10⁻⁸ Ω·m = 10 nΩ·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.
