How to convert electrical conductance

Conductance is the opposite of resistance. It is measured in siemens (S), which is the same as the older unit called the mho.

Every electrical conductance unit is a fixed multiple of one base unit, the S. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert mS to S, multiply by 0.001. To go the other way, divide by 0.001.

The converter above does this for you and shows the exact formula under the result.

Worked examples

10 mS = 0.010 S10 × 0.001 = 0.010 S.
25 S = 25 mS25 × 1 = 25 mS.
5 µS = 0.005 mS5 × 0.001 = 0.005 mS.
50 kS = 50,000 S50 × 1,000 = 50,000 S.

Frequently asked questions

How is conductance related to resistance?

Conductance in siemens is 1 divided by resistance in ohms. A 10 Ω resistor has a conductance of 0.1 S.

How do I convert mS to S?

Multiply the value in mS by 0.001 to get S. For example, 10 mS = 0.010 S.

How many S is 1 mS?

1 mS = 0.001 S, and 1 S = 1 mS.

Does this electrical conductance converter work offline?

Yes. After the page has loaded once, all calculations run in your browser, so it keeps working without an internet connection.
