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 Gigaohm-metres
The gigaohm-metre (GΩ·m) equals 10⁹ Ω·m, the scale for excellent insulating materials and ultra-pure liquids. Fused silica (quartz glass) has resistivity ≈ 10⁴-10⁵ GΩ·m at room temperature; ultra-pure deionised water is ≈18 MΩ·cm = 180 kΩ·m; synthetic sapphire is ≈1-10⁴ GΩ·m depending on temperature. 1 GΩ·m = 10⁹ Ω·m = 10³ MΩ·m.
