About Megaohm-metres
The megaohm-metre (MΩ·m) equals 10⁶ Ω·m, the scale for polymer insulators and high-purity dielectric ceramics. PTFE (Teflon) has resistivity ~10⁷ MΩ·m; polypropylene cable insulation is 10⁴-10⁶ MΩ·m; IEC 60093 surface and volume resistivity measurements on solid insulating materials are quoted in MΩ·m. 1 MΩ·m = 10⁶ Ω·m = 10³ kΩ·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.
