How the formula works
Both attosiemens and decasiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attosiemens by 1.000000e-19 to get decasiemens. To reverse the conversion, multiply a decasiemens value by 1.000000e+19 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 Decasiemens (daS)?
A Decasiemens (daS) equals 10 siemens(s), a scaled unit of electrical conductance used for deca-scale electrical work.
How do I convert attosiemens to decasiemens?
Multiply the attosiemens value by 1.000000e-19 to get the equivalent in decasiemens. For example, 5 aS × 1.000000e-19 = 5.000000e-19 daS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-19 is an exact, non-rounded value.
Can I convert decasiemens back to attosiemens?
Yes. Divide the decasiemens value by 1.000000e-19, or multiply it by 1.000000e+19, to get attosiemens.
