What I expect to see is:
#include 
#include 
#include 
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.
could you give me an example? That is how should the statement

 l2 = 1.0 * miles; // compile error

be modified?

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