How the formula works
Both attosiemens and millisiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attosiemens by 1.000000e-15 to get millisiemens. To reverse the conversion, multiply a millisiemens value by 1.000000e+15 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 Millisiemens (mS)?
A Millisiemens (mS) equals 1/1,000 siemens(s), a scaled unit of electrical conductance used for milli-scale electrical work.
How do I convert attosiemens to millisiemens?
Multiply the attosiemens value by 1.000000e-15 to get the equivalent in millisiemens. For example, 5 aS × 1.000000e-15 = 5.000000e-15 mS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-15 is an exact, non-rounded value.
Can I convert millisiemens back to attosiemens?
Yes. Divide the millisiemens value by 1.000000e-15, or multiply it by 1.000000e+15, to get attosiemens.
