Conversions
An electric conductance converter restates one conductance value across siemens, the common SI prefix ladder, and the older mho naming convention that still appears in some legacy references. It is useful when you want one clean sheet that anchors a measured or specified conductance back to siemens without mixing it up with resistance or conductivity.
This page converts a non-negative conductance across nanosiemens, microsiemens, millisiemens, siemens, kilosiemens, megasiemens, and mho.
That keeps small sensor and solution-admittance readings readable while still supporting larger conductance values used in heavier electrical contexts and older documentation.
The converter first resolves the entered value into siemens. Every other result is then a scaled form of that same conductance, which is why the siemens baseline stays visible in the summary.
Keeping that baseline in view is especially helpful when the same magnitude could be written naturally as µS, mS, or S depending on the measurement range.
1 S = 1,000 mS = 1,000,000 µS = 1,000,000,000 nS
The common SI prefix ladder changes readability without changing the underlying conductance.
1 kS = 1,000 S; 1 MS = 1,000,000 S
Large-prefix forms keep unusually high conductance values readable.
1 mho = 1 S
Mho is the historical alias for siemens and is included so older references can be read directly.
Conductance describes the ease of current flow for a whole path or device under stated conditions. Conductivity is a material property per unit geometry. Converting one does not automatically convert the other.
That distinction matters because a high-conductivity material can still produce a modest total conductance if the path is long, thin, or otherwise geometry-limited.
This calculator does not infer geometry, resistance, admittance of reactive elements, or material conductivity from a conductance value. It converts the conductance quantity itself between units only.
Use it as an educational and planning reference. If the next step depends on geometry, resistance, or material properties, switch to the calculator that models that relationship directly.
Frequently asked questions
No. Mho is the older name for the same unit. A value of 1 mho is exactly 1 siemens.
Because small conductance values are often easier to read in microsiemens or millisiemens. The unit choice changes readability, not the underlying electrical quantity.
No. Conductivity is a material property and depends on geometry when translated into total conductance. This page only converts conductance units.
