How the formula works
Both siemens and centisiemens measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in siemens by 100 to get centisiemens. To reverse the conversion, multiply a centisiemens value by 0.01 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 Centisiemens (cS)?
A Centisiemens (cS) equals 1/100 siemens(s), a scaled unit of electrical conductance used for centi-scale electrical work.
How do I convert siemens to centisiemens?
Multiply the siemens value by 100 to get the equivalent in centisiemens. For example, 5 S × 100 = 500 cS.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 100 is an exact, non-rounded value.
Can I convert centisiemens back to siemens?
Yes. Divide the centisiemens value by 100, or multiply it by 0.01, to get siemens.
