What I expect to see is:

void main(){
    using namespace boost::units;
    using namespace boost::units::si;
    using namespace boost::units::us;
    quantity l1;
    l1 = 1000.0 * meters;
    quantity l2;
    l2 = 1.0 * miles; // compile error
    quantity l3 = l1 + l2;
}
and I expect this to pretty much work.  The documentation says " Implicit 
conversions between unit systems are allowed only when the reduced units are 
identical, allowing, for example, trivial conversions between equivalent 
units in different systems (such as SI seconds and CGS seconds)" so I 
expected that it can convert miles into kilometers.
Try static_cast.

This is a 
disappointment - but I'll assume that the authors have a good reason for 
this.
