You mean like the traditional units program available on virtually all Unix
machines?

    $ units
    2084 units, 71 prefixes, 32 nonlinear units

    You have: 1 lightyear/fortnight
    You want: m/s
            * 7.8213711e+09
            / 1.2785482e-10

That's the program I suggested writing a function to hand this work off to
(presumably in the form of a dynamic library). Keep the postgres code agnostic
about the semantics of the units. As long as you stick to linear units then
Postgres can treat them as opaque strings.
