How the formula works
Both millisiemens and siemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in millisiemens by 0.001 to get siemens. To reverse the conversion, multiply a siemens value by 1000 to get back to millisiemens.
Frequently asked questions
What is Millisiemens (mS)?
A Millisiemens (mS) equals 1/1,000 siemens(s), a scaled unit of electrical conductance used for milli-scale electrical work.
What is Siemens (S)?
The siemens (S) is the SI unit of electrical conductance, the reciprocal of resistance.
How do I convert millisiemens to siemens?
Multiply the millisiemens value by 0.001 to get the equivalent in siemens. For example, 5 mS × 0.001 = 0.005 S.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert siemens back to millisiemens?
Yes. Divide the siemens value by 0.001, or multiply it by 1000, to get millisiemens.
