How the formula works
Both femtosiemens and decasiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtosiemens by 1.000000e-16 to get decasiemens. To reverse the conversion, multiply a decasiemens value by 1.000000e+16 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 Decasiemens (daS)?
A Decasiemens (daS) equals 10 siemens(s), a scaled unit of electrical conductance used for deca-scale electrical work.
How do I convert femtosiemens to decasiemens?
Multiply the femtosiemens value by 1.000000e-16 to get the equivalent in decasiemens. For example, 5 fS × 1.000000e-16 = 5.000000e-16 daS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-16 is an exact, non-rounded value.
Can I convert decasiemens back to femtosiemens?
Yes. Divide the decasiemens value by 1.000000e-16, or multiply it by 1.000000e+16, to get femtosiemens.
