How the formula works
Both millisiemens and attosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in millisiemens by 1.000000e+15 to get attosiemens. To reverse the conversion, multiply a attosiemens value by 1.000000e-15 to get back to millisiemens.
Frequently asked questions
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.
What is Attosiemens (aS)?
An Attosiemens (aS) equals 1e-18 siemens(s), a scaled unit of electrical conductance used for atto-scale electrical work.
How do I convert millisiemens to attosiemens?
Multiply the millisiemens value by 1.000000e+15 to get the equivalent in attosiemens. For example, 5 mS × 1.000000e+15 = 5.000000e+15 aS.
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 attosiemens back to millisiemens?
Yes. Divide the attosiemens value by 1.000000e+15, or multiply it by 1.000000e-15, to get millisiemens.
