How the formula works
Both femtosiemens and kilosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtosiemens by 1.000000e-18 to get kilosiemens. To reverse the conversion, multiply a kilosiemens value by 1.000000e+18 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 Kilosiemens (kS)?
A Kilosiemens (kS) equals 1,000 siemens(s), a scaled unit of electrical conductance used for kilo-scale electrical work.
How do I convert femtosiemens to kilosiemens?
Multiply the femtosiemens value by 1.000000e-18 to get the equivalent in kilosiemens. For example, 5 fS × 1.000000e-18 = 5.000000e-18 kS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-18 is an exact, non-rounded value.
Can I convert kilosiemens back to femtosiemens?
Yes. Divide the kilosiemens value by 1.000000e-18, or multiply it by 1.000000e+18, to get femtosiemens.
