How to convert millisiemens to siemens
S = mS × 0.001Multiply the value in millisiemens by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).
A millisiemens is smaller than a siemens: it takes 1,000 millisiemens to make one siemens.

About the units
Millisiemens (mS)
The millisiemens (mS) is a unit of electric conductance in the International System of Units (SI). One millisiemens equals 0.001 siemens (S).
Siemens (S)
One ampere per volt; the reciprocal of an ohm.
Frequently asked questions
How many siemens are in one millisiemens?
There are 0.001 siemens in one millisiemens, and this value is exact by definition.
How do I convert millisiemens to siemens?
Multiply the number of millisiemens by 0.001. For example, 10 mS × 0.001 = 0.01 S.
How many millisiemens are in one siemens?
One siemens equals 1,000 millisiemens. That is the reverse factor, 1 ÷ 0.001.
What is 10 millisiemens in siemens?
10 mS = 0.01 S.
Is this mS to S converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
