Hi Yongchun  -

You may be interested in the example OntologyInterop2, which is live online 
at www.reengineeringllc.com.  It illustrates how to reason about units and 
to convert between them when necessary.

The notation is different from OWL (more end-user-ish).  But it allows all 
sorts of useful inferences that do not seem to be possible in OWL itself.

                                 Cheers,   -- Adrian
