Roger,

just a quick observation:

No, not in the sense that they are owl:sameIndividualAs, for a simple 
reason. If they were the same resource, it would be true that

     _:x  rdf:value  "1.0"
     _:x  my:units   "inch"
     _:x  rdf:value  "2.54"
     _:x  my:units   "centimeter"

and therefore,

     _:x  rdf:value  "1.0"
     _:x  my:units   "centimeter"

That's obviously not what you want :-)
