How to convert siemens to millisiemens
Conductance uses siemens (S = A/V), the reciprocal of ohms. Conductivity in S/m or µS/cm includes a length dimension and cannot be obtained from conductance alone without cell geometry.
mS = S × 1000One siemens is 1000 millisiemens, so a single multiplication converts any value.
10,000 mS = 10 × 1000Siemens to millisiemens conversion table

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
