About Abohm-centimetres
The abohm-centimetre (abΩ·cm) is the resistivity unit of the CGS-EMU system, equal to 10⁻⁹ Ω × 0.01 m = 10⁻¹¹ Ω·m. It appears in nineteenth-century electromagnetic analysis of telegraph cables and dynamo windings; silver, the best metallic conductor, has resistivity ≈1.59 nΩ·m = 159 abΩ·cm. 1 abΩ·cm = 10⁻¹¹ Ω·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.
