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

About the units
Siemens (S)
One ampere per volt; the reciprocal of an ohm.
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).
Frequently asked questions
How many millisiemens are in one siemens?
There are 1,000 millisiemens in one siemens, and this value is exact by definition.
How do I convert siemens to millisiemens?
Multiply the number of siemens by 1,000. For example, 10 S × 1,000 = 10,000 mS.
How many siemens are in one millisiemens?
One millisiemens equals 0.001 siemens. That is the reverse factor, 1 ÷ 1,000.
What is 10 siemens in millisiemens?
10 S = 10,000 mS.
Is this S to mS 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.
