How the formula works
Both attosiemens and femtosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attosiemens by 0.001 to get femtosiemens. To reverse the conversion, multiply a femtosiemens value by 1000 to get back to attosiemens.
Frequently asked questions
What is Attosiemens (aS)?
An Attosiemens (aS) equals 1e-18 siemens(s), a scaled unit of electrical conductance used for atto-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 attosiemens to femtosiemens?
Multiply the attosiemens value by 0.001 to get the equivalent in femtosiemens. For example, 5 aS × 0.001 = 0.005 fS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert femtosiemens back to attosiemens?
Yes. Divide the femtosiemens value by 0.001, or multiply it by 1000, to get attosiemens.
