How the formula works
Both siemens and decisiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in siemens by 10 to get decisiemens. To reverse the conversion, multiply a decisiemens value by 0.1 to get back to siemens.
Frequently asked questions
What is Siemens (S)?
The siemens (S) is the SI unit of electrical conductance, the reciprocal of resistance.
What is Decisiemens (dS)?
A Decisiemens (dS) equals 1/10 siemens(s), a scaled unit of electrical conductance used for deci-scale electrical work.
How do I convert siemens to decisiemens?
Multiply the siemens value by 10 to get the equivalent in decisiemens. For example, 5 S × 10 = 50 dS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 10 is an exact, non-rounded value.
Can I convert decisiemens back to siemens?
Yes. Divide the decisiemens value by 10, or multiply it by 0.1, to get siemens.
