How the formula works
Both microsiemens and femtosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microsiemens by 1.000000e+09 to get femtosiemens. To reverse the conversion, multiply a femtosiemens value by 1.000000e-09 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 Femtosiemens (fS)?
A Femtosiemens (fS) equals 1e-15 siemens(s), a scaled unit of electrical conductance used for femto-scale electrical work.
How do I convert microsiemens to femtosiemens?
Multiply the microsiemens value by 1.000000e+09 to get the equivalent in femtosiemens. For example, 5 uS × 1.000000e+09 = 5.000000e+09 fS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+09 is an exact, non-rounded value.
Can I convert femtosiemens back to microsiemens?
Yes. Divide the femtosiemens value by 1.000000e+09, or multiply it by 1.000000e-09, to get microsiemens.
