One siemens equals exactly 1,000 millisiemens (mS). The milli- prefix denotes one-thousandth of the base unit.
Electrical conductance is the reciprocal of resistance, measuring how easily current flows through a material. It is measured in siemens (S) in the SI system.
Millisiemens are common in water quality measurements (conductivity meters), semiconductor characterization, and electrochemistry.
Multiply the conductance in siemens by 1,000. For example, 0.25 S × 1,000 = 250 mS.
