(electricity) A unit of conductance in the electromagnetic centimeter-gram-second system of units equal to 109 mhos. Abbreviated (aΩ)-1. Also known as absiemens (aS).
electric conductance Metric-c.g.s. The absolute mho of the e.m.u. system, for a steady current identically abA/abV, and identically reciprocal abΩ. 1 abmho = 1 GS.
