How the formula works
Both volt and attosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in volts by 1.000000e+18 to get attosiemens. To reverse the conversion, multiply a attosiemens value by 1.000000e-18 to get back to volts.
Frequently asked questions
What is Volt (V)?
The volt (V) is the SI unit of electric potential difference, the "push" that drives current through a circuit.
What is Attosiemens (aS)?
A Attosiemens (aS) equals 1e-18 siemens(s), a scaled unit of electrical conductance used for atto-scale electrical work.
How do I convert volts to attosiemens?
Multiply the volt value by 1.000000e+18 to get the equivalent in attosiemens. For example, 5 V × 1.000000e+18 = 5.000000e+18 aS.
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 attosiemens back to volts?
Yes. Divide the attosiemens value by 1.000000e+18, or multiply it by 1.000000e-18, to get volts.
