See e.g.
http://www.awprofessional.com/articles/article.asp?p=375705&seqNum=1, which describes a framework for enforcing dimensional correctness; extension to handle automatic units declaration and conversion is not too hard (the hardest part is probably that a naive implementation will have lots of rounding error -- probably want to implement it using rationals rather than floating point).
