How the formula works
Both attosiemens and gigasiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attosiemens by 1.000000e-27 to get gigasiemens. To reverse the conversion, multiply a gigasiemens value by 1.000000e+27 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 Gigasiemens (GS)?
A Gigasiemens (GS) equals 1e+9 siemens(s), a scaled unit of electrical conductance used for giga-scale electrical work.
How do I convert attosiemens to gigasiemens?
Multiply the attosiemens value by 1.000000e-27 to get the equivalent in gigasiemens. For example, 5 aS × 1.000000e-27 = 5.000000e-27 GS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-27 is an exact, non-rounded value.
Can I convert gigasiemens back to attosiemens?
Yes. Divide the gigasiemens value by 1.000000e-27, or multiply it by 1.000000e+27, to get attosiemens.
