About these units

The microsiemens (µS) is a metric unit of electric conductance, equal to 0.000001 siemens.

The millisiemens (mS) is a metric unit of electric conductance, equal to 0.001 siemens.

Going the other way, 1 millisiemens = 1,000 microsiemens. Conductance is the reciprocal of resistance: a 1 ohm resistor conducts 1 siemens. The older name mho, ohm spelled backwards, is still printed on many instruments and means exactly the same thing.
