Runtime conversion are also something I am interrested. Are you 
following the lead of :

I think that we could layer things this way :
LAYER 3: any_quantity
runtime dimensional analysis and conversion
LAYER 2: any_quantity
compile time dimensional analysis and runtime conversion
LAYER 1: quantity<unit>
the actual library
Fwiw: this runtime variant would be really welcome. In our application we 
calculate some data with various units (e.g. m/s, m) which gets plotted. The 
plotter just talks to the base class of the data, like:

struct Data
{
   Unit    GetUnit () const;
   double  GetValue(size_t nIndex) const;
};

Also the user is able to specify his display units (e.g. cm instead of m), and 
we use the runtime unit for scaling the physical quantities.

your article than new. Prune quoted stuff.')
