How the formula works
Both microsiemens and millisiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microsiemens by 0.001 to get millisiemens. To reverse the conversion, multiply a millisiemens value by 1000 to get back to microsiemens.
Frequently asked questions
What is Microsiemens (uS)?
A Microsiemens (uS) equals 1e-06 siemens(s), a scaled unit of electrical conductance used for micro-scale electrical work.
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.
How do I convert microsiemens to millisiemens?
Multiply the microsiemens value by 0.001 to get the equivalent in millisiemens. For example, 5 uS × 0.001 = 0.005 mS.
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 millisiemens back to microsiemens?
Yes. Divide the millisiemens value by 0.001, or multiply it by 1000, to get microsiemens.
