That just goes to show it is scientific in 'essence'. HL7 could
well be specifying a test which involves Pascals or Ohms or even
tropical years but all of that is a barrier to entry to the person
ordering a few days consultancy. (Do they mean 'tropical days',
'lunar days'...? No, just 'days'. How many parsecs is that?). If they
want 5 troy ounces of gold that translates as 5 '20's of gold. OK
it works but it doesn't really help the app writer that they have
to cater for codes like that and who knows which of them out of
all those in the list. They could all have to be translatable just
in case. Better, surely, to allow free-text units to be stated
so the UOM code can be safely subsetted out so the app writer doesn't
have to bother with it. Trouble is that may break the ATG alignment.

Still there's all sorts of things I can order from my grocer:
What about 6 bottles of wine, 750cl each. I notice you can easily
order a number of arbitrary powers of milk :-) or a straight
'Gunter's chain' of who knows what. I may one day want to buy a
Planck constant of lightwaves I suppose :-)
