For this purpose I'm pretty ok with Hungarian notation. Haven't found a nice type based solution yet. I tried to roll my own, but looking back I'm not really satisfied with it. Besides, I'm no longer doing anything with physics calculations.

Scala's squants library is a nice implementation of units-of-measure/dimensional-analysis http://www.squants.com
In particular it uses types for dimensions; whilst units are just constructors. Hence `Meters(2)` and `Microns(7)` have the same type (`Length`).

You might find the Squants library for Scala interesting; it even seems like an apt usage of some oft-questioned language features.
