How the formula works
Both attosiemens and siemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attosiemens by 1.000000e-18 to get siemens. To reverse the conversion, multiply a siemens value by 1.000000e+18 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 Siemens (S)?
The siemens (S) is the SI unit of electrical conductance, the reciprocal of resistance.
How do I convert attosiemens to siemens?
Multiply the attosiemens value by 1.000000e-18 to get the equivalent in siemens. For example, 5 aS × 1.000000e-18 = 5.000000e-18 S.
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 siemens back to attosiemens?
Yes. Divide the siemens value by 1.000000e-18, or multiply it by 1.000000e+18, to get attosiemens.
