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

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).
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).
Frequently asked questions
How many microsiemens are in one millisiemens?
There are 1,000 microsiemens in one millisiemens, and this value is exact by definition.
How do I convert millisiemens to microsiemens?
Multiply the number of millisiemens by 1,000. For example, 10 mS × 1,000 = 10,000 µS.
How many millisiemens are in one microsiemens?
One microsiemens equals 0.001 millisiemens. That is the reverse factor, 1 ÷ 1,000.
What is 10 millisiemens in microsiemens?
10 mS = 10,000 µS.
Is this mS to µS 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.
