I don't think that separate columns for each type of unit would be a
good choice. I agree with Roy that the most straightforward approach
would be to just convert to a standard unit. Where I work this is what
most people (including me) do.

However, if you want an alternate approach, you could store the value
in one column and the units in another.

And as long as you never need to sort on that column, then there is probably no drawback. Though personally if I didn't need to sort, I would probably use a string. JScience should cope with parsing and formatting well enough, and it guarantees no loss in precision.
