How to Convert Millisiemens to Siemens

To convert a millisiemens measurement to a siemens measurement, divide the electrical conductance by the conversion ratio.

Since one siemens is equal to 1,000 millisiemens, you can use this simple formula to convert:

siemens = millisiemens ÷ 1,000

The electrical conductance in siemens is equal to the millisiemens divided by 1,000.

For example, here's how to convert 5,000 millisiemens to siemens using the formula above.
5,000 mS = (5,000 ÷ 1,000) = 5 S

Millisiemens and siemens are both units used to measure electrical conductance. Keep reading to learn more about each unit of measure.


The millisiemens is the SI defined unit equal to the millimho. One millisiemens is the electrical conductance equal to 1/1,000 of a siemens, which is equal to one ampere per volt.

The millisiemens is a multiple of the siemens, which is the SI derived unit for electrical conductance. In the metric system, "milli" is the prefix for 10-3. Millisiemens can be abbreviated as mS; for example, 1 millisiemens can be written as 1 mS.


One siemens is the electrical conductance equal to an increase in current of one ampere for every increase in electrical potential difference of one volt. The siemens is the SI defined unit equal to the mho, and is the reciprocal of the resistance in ohms.

The siemens is the SI derived unit for electrical conductance in the metric system. Siemens can be abbreviated as S; for example, 1 siemens can be written as 1 S.
