Use the Electric Conductance Converter
Electric Conductance formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in S.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (S) |
Electric Conductance examples
S to mS
10 S = 10,000 mS.
S to µS
10 S = 10,000,000 µS.
mS to S
10 mS = 0.01 S.
How to calculate Electric Conductance step by step
- Choose the starting unit and the target unit.
- Enter your value.
- Read the converted value, plus the conversion factor in both directions.

How to read your Electric Conductance result
The siemens is the SI unit of electric conductance, the reciprocal of resistance. One siemens equals one reciprocal ohm. A millisiemens is 0.001 S and a microsiemens is 1×10⁻⁶ S.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 S |
|---|---|---|---|
| Siemens | S | 1 S = 1 S | 1 S |
| Millisiemens | mS | 1 mS = 0.001 S | 1,000 mS |
| Microsiemens | µS | 1 µS = 0.000001 S | 1,000,000 µS |
| Kilosiemens | kS | 1 kS = 1,000 S | 0.001 kS |
| Mho | ℧ | 1 ℧ = 1 S | 1 ℧ |
| Micromho | µ℧ | 1 µ℧ = 0.000001 S | 1,000,000 µ℧ |
| Ampere per volt | A/V | 1 A/V = 1 S | 1 A/V |
Common mistakes when calculating Electric Conductance
- Confusing conductance (S) with conductivity (S/m).
- Mixing mS and µS, which differ by 1,000.
- Using conductance when resistance is meant: one is the reciprocal of the other.
Electric Conductance FAQ
How many S is 1 mS?
1 mS is 0.001 S.
How is siemens related to ohm?
1 S = 1/Ω, so a 2 Ω resistor has a conductance of 0.5 S.
What was the old name for the siemens?
The mho, an ohm spelled backwards, equal to 1 S.
What is the base unit for electric conductance?
This converter uses siemens (S) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two electric conductance units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many millisiemens are in 1 siemens?
1 S = 1,000 mS.
How many microsiemens are in 1 siemens?
1 S = 1,000,000 µS.
How many siemens are in 1 millisiemens?
1 mS = 0.001 S.
Which electric conductance units does this converter support?
It covers 7 units: siemens (S), millisiemens (mS), microsiemens (µS), kilosiemens (kS), mho (℧), micromho (µ℧), ampere per volt (A/V).
How accurate is the electric conductance converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
