I had some fun with http://www.w3.org/2007/ont/unit ...

I get ex:track ex:length [ :chain 20.0; :foot 1320.0; :furlong 2.0; :inch 15840.0; :m 402.336; :mile 0.25; :yard 440.0 ] . and from (un:foot un:hz) o2:chain fps. bullet speed [ fps 4000 ]. I get: ex:bullet ex:speed [ ex:fps 4000; :mps 1219.2 ] . -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
