About Abohms
The abohm (abΩ) is the resistance unit of the CGS-EMU system, defined as 1 abvolt per abampere = 10⁻⁸ V / 10 A = 10⁻⁹ Ω, exactly equal to 1 nΩ. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts for low-resistance measurements of copper conductors, motor windings, and cable joints. 1 abΩ = 10⁻⁹ Ω = 1 nΩ.
About Megaohms
The megaohm (MΩ) equals 10⁶ Ω, the scale of insulation testing and high-impedance analogue circuit design. Insulation testers (meggers) measure cable and motor winding insulation from 0.1-1000 MΩ; pH electrode output impedance is 10-500 MΩ; precision op-amp feedback networks use 1-10 MΩ resistors to set very high signal-source impedance. 1 MΩ = 10⁶ Ω = 10³ kΩ.
