A very simple but effective system that I have used quite a lot for
"computation with units" is a Python module called unum ("Unit numbers"):

I suppose what makes this (marginally) "on-topic" is that you could use
it within pgpythonu, but I haven't tried that myself. In particular,
you'd have to serialize the unum objects to store them.
