1 millisiemens equals 0.001 siemens
How to convert millisiemens to siemens
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.
S = mS × 0.001One millisiemens is 0.001 siemens, so a single multiplication converts any value.
0.01 S = 10 × 0.001Millisiemens to siemens 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.
