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 Microsiemens

The microsiemens (µS) equals 10⁻⁶ S, the standard unit for water-quality conductivity measurement and analogue signal-path impedance. Drinking water has conductivity of 50-500 µS/cm; a 1 MΩ resistor presents 1 µS; conductivity meters for hydroponics and aquaculture read directly in microsiemens or millisiemens per centimetre. 1 µS = 10⁻³ mS = 10⁻⁶ S.
