I remember I missed examples in the documentation of units in order to 
get the abstract
concpets to fall into place. In lieu of recipes on units on 
<http://wwww.schemecookbook.org>
I''ll just link to the discussion, where I got help on units.

Are there other examples around? Perhaps we could use them for the cookbook.
