How the formula works
Both femtosiemens and gigasiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtosiemens by 1.000000e-24 to get gigasiemens. To reverse the conversion, multiply a gigasiemens value by 1.000000e+24 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 Gigasiemens (GS)?
A Gigasiemens (GS) equals 1e+9 siemens(s), a scaled unit of electrical conductance used for giga-scale electrical work.
How do I convert femtosiemens to gigasiemens?
Multiply the femtosiemens value by 1.000000e-24 to get the equivalent in gigasiemens. For example, 5 fS × 1.000000e-24 = 5.000000e-24 GS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-24 is an exact, non-rounded value.
Can I convert gigasiemens back to femtosiemens?
Yes. Divide the gigasiemens value by 1.000000e-24, or multiply it by 1.000000e+24, to get femtosiemens.
