Conversion Formula
abS = MS × 0.001
About Megasiemens
The megasiemens (MS) equals 10⁶ S, the scale for very-low-resistance metallic structures such as thick busbars and short heavy-gauge connectors. A 10 cm long, 1 cm² copper bar has conductance of roughly 600 MS; aluminium overhead grid feeders have per-span conductances in the megasiemens range; conductance of grain boundaries in polycrystalline conductors at cryogenic temperatures reaches megasiemens. 1 MS = 10⁶ S = 10³ kS.
About Absiemens
The absiemens (abS) is the conductance unit of the CGS-EMU system, equal to 1/abΩ = 1/(10⁻⁹ Ω) = 10⁹ S, exactly identical to 1 GS in SI. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts; 1 abS corresponds to the conductance of a 1 nΩ connection typical of large cryogenically cooled bus joints or welded thick-copper structures. 1 abS = 10⁹ S = 1 GS.
