To convert a measurement in siemens to a measurement in millisiemens, multiply the electrical conductance by the following conversion ratio: 1,000 millisiemens/siemens.

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

millisiemens = siemens × 1,000

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

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

How Many Millisiemens Are in a Siemens?

There are 1,000 millisiemens in a siemens, which is why we use this value in the formula above.

1 S = 1,000 mS

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

What Is a Siemens?

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.

What Is a Millisiemens?

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 thousandths, or 10-3. Millisiemens can be abbreviated as mS; for example, 1 millisiemens can be written as 1 mS.
