How the formula works
Both millisiemens and microsiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in millisiemens by 1000 to get microsiemens. To reverse the conversion, multiply a microsiemens value by 0.001 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 Microsiemens (uS)?
A Microsiemens (uS) equals 1e-06 siemens(s), a scaled unit of electrical conductance used for micro-scale electrical work.
How do I convert millisiemens to microsiemens?
Multiply the millisiemens value by 1000 to get the equivalent in microsiemens. For example, 5 mS × 1000 = 5000 uS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert microsiemens back to millisiemens?
Yes. Divide the microsiemens value by 1000, or multiply it by 0.001, to get millisiemens.
