Siemens and Millisiemens describe the same electrical conductance measurement in different units. Converting between them makes values easier to compare when different unit systems are used.
How to convert Siemens to Millisiemens (S to mS)
To convert Siemens to Millisiemens, multiply by 1000. The formula is Siemens × 1000 = Millisiemens. See the example below.
1 Siemens = 1 × 1000 = 1000 Millisiemens
Siemens is a unit of measurement for electric conductance. A device is considered to have electric conductance of one siemens if the electric current through this device will increase by one ampere for every increase of one volt of electric potential difference across the device. The symbol for Siemens is S.
Millisiemens is a unit of measurement for electric conductance. Millisiemens is decimal fraction of electric conductance unit siemens. One millisiemens is equal to 0.001 siemens. The symbol for Millisiemens is mS.
