How the formula works
Both femtosiemens and attosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtosiemens by 1000 to get attosiemens. To reverse the conversion, multiply a attosiemens value by 0.001 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 Attosiemens (aS)?
An Attosiemens (aS) equals 1e-18 siemens(s), a scaled unit of electrical conductance used for atto-scale electrical work.
How do I convert femtosiemens to attosiemens?
Multiply the femtosiemens value by 1000 to get the equivalent in attosiemens. For example, 5 fS × 1000 = 5000 aS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert attosiemens back to femtosiemens?
Yes. Divide the attosiemens value by 1000, or multiply it by 0.001, to get femtosiemens.
