millisiemens to siemens
Convert millisiemens (mS) to siemens (S). Use an editable electrical conductance converter, conversion formula, and reference table.
1 mS = 0.001 S
Conversion formula
One millisiemens equals 0.001 siemens. Multiply your value in millisiemens by this factor to get siemens. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 millisiemens:5 × 0.001 = 0.005 S
Conversion table
| millisiemens (mS) | siemens (S) |

| 1000 | 1 |
About these measurements
Conductance is the reciprocal of resistance.
The base reference used here is the siemens. One millisiemens is 0.001 base units; one siemens is 1 base units.
Important distinctions
To convert resistance into conductance, take a reciprocal. A direct unit conversion does not do that.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert mS to S?
Multiply the quantity in mS by 0.001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the siemens to millisiemens converter.
