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

About the units
Microsiemens (µS)
The microsiemens (µS) is a unit of electric conductance in the International System of Units (SI). One microsiemens equals 0.000001 siemens (S).
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 microsiemens?
There are 0.001 millisiemens in one microsiemens, and this value is exact by definition.
How do I convert microsiemens to millisiemens?
Multiply the number of microsiemens by 0.001. For example, 10 µS × 0.001 = 0.01 mS.
How many microsiemens are in one millisiemens?
One millisiemens equals 1,000 microsiemens. That is the reverse factor, 1 ÷ 0.001.
What is 10 microsiemens in millisiemens?
10 µS = 0.01 mS.
Is this µS 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.
