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 Microohms
The microohm (µΩ) equals 10⁻⁶ Ω, the practical scale for contact resistance testing, bus-bar joints, and circuit-breaker contacts. A well-made bolted bus-bar connection has contact resistance below 50 µΩ; a 25 mm² copper conductor has resistance of about 0.7 µΩ/mm; IEC 60947 specifies acceptance limits for switchgear contacts in microohms. 1 µΩ = 10⁻³ mΩ = 10³ nΩ.
