I would have thought someone would have come up with an ontology for volts and other electrical units already...?

The use of electical units was just an Example. The Problem I want to address ist the n:m mapping of RDF/OWL-Structures. Currently there is only 1:1 Class/Property mapping in the art:

<unit:V rdf:ID="V">
   <owl:sameAs rdf:resource="&unit;Volt" />

I think that is a limitation of OWL; but maybe someone is genius enought to find a better solution than mine.

But u're right - maybe should posted on techof...
