Ah, that works as intended - do you think you could make it more explicit 
in the documentation how to do this?  E.g., as part of "runtime conversions",

...
typedef us_dollar_base_unit::unit_type us_dollar;
typedef euro_base_unit::unit_type euro;

void foo() {   
   quantity<us_dollars> dollars(10.0*us_dollars);
   quantity<euro> euros(dollars);

   std::cout << dollars << " is " << euros << std::endl;
}

Thanks,
Justin
