siemens to millisiemens
Convert siemens (S) to millisiemens (mS). Use an editable electrical conductance converter, conversion formula, and reference table.
1 S = 1,000 mS
Conversion formula
One siemens equals 1,000 millisiemens. Multiply your value in siemens by this factor to get millisiemens. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 siemens:5 × 1,000 = 5,000 mS

About these measurements
Conductance is the reciprocal of resistance.
The base reference used here is the siemens. One siemens is 1 base units; one millisiemens is 0.001 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 S to mS?
Multiply the quantity in S by 1,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the millisiemens to siemens converter.
