How the formula works
Both femtosiemens and millisiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtosiemens by 1.000000e-12 to get millisiemens. To reverse the conversion, multiply a millisiemens value by 1.000000e+12 to get back to femtosiemens.
Frequently asked questions
What is Femtosiemens (fS)?
A Femtosiemens (fS) equals 1e-15 siemens(s), a scaled unit of electrical conductance used for femto-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 femtosiemens to millisiemens?
Multiply the femtosiemens value by 1.000000e-12 to get the equivalent in millisiemens. For example, 5 fS × 1.000000e-12 = 5.000000e-12 mS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-12 is an exact, non-rounded value.
Can I convert millisiemens back to femtosiemens?
Yes. Divide the millisiemens value by 1.000000e-12, or multiply it by 1.000000e+12, to get femtosiemens.
