How the formula works
Both decisiemens and femtosiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decisiemens by 1.000000e+14 to get femtosiemens. To reverse the conversion, multiply a femtosiemens value by 1.000000e-14 to get back to decisiemens.
Frequently asked questions
What is Decisiemens (dS)?
A Decisiemens (dS) equals 1/10 siemens(s), a scaled unit of electrical conductance used for deci-scale electrical work.
What is Femtosiemens (fS)?
A Femtosiemens (fS) equals 1e-15 siemens(s), a scaled unit of electrical conductance used for femto-scale electrical work.
How do I convert decisiemens to femtosiemens?
Multiply the decisiemens value by 1.000000e+14 to get the equivalent in femtosiemens. For example, 5 dS × 1.000000e+14 = 5.000000e+14 fS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+14 is an exact, non-rounded value.
Can I convert femtosiemens back to decisiemens?
Yes. Divide the femtosiemens value by 1.000000e+14, or multiply it by 1.000000e-14, to get decisiemens.
