How the formula works
Both decasiemens and femtosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decasiemens by 1.000000e+16 to get femtosiemens. To reverse the conversion, multiply a femtosiemens value by 1.000000e-16 to get back to decasiemens.
Frequently asked questions
What is Decasiemens (daS)?
A Decasiemens (daS) equals 10 siemens(s), a scaled unit of electrical conductance used for deca-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 decasiemens to femtosiemens?
Multiply the decasiemens value by 1.000000e+16 to get the equivalent in femtosiemens. For example, 5 daS × 1.000000e+16 = 5.000000e+16 fS.
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 femtosiemens back to decasiemens?
Yes. Divide the femtosiemens value by 1.000000e+16, or multiply it by 1.000000e-16, to get decasiemens.
