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 Milliohms
The milliohm (mΩ) equals 10⁻³ Ω, the scale of precision current-sensing shunts, relay contacts, and PCB trace resistance. Current-sensing shunts of 1-10 mΩ allow high-current measurement by detecting the millivolt drop they produce; electrical continuity standards flag connections above a few milliohms; DC winding resistance of large motor coils is typically 0.1-10 mΩ. 1 mΩ = 10⁻³ Ω = 10³ µΩ.
