I am having trouble seeing how to use mixed units.
The program below compiles and runs.
See the changes I "wish" I could make as comments.

using namespace std;

int main() {
 static const si::length m = si::meter;
 // static const si::length ft = ???;
 typedef quantitysi::length Length;
 Length x = 2.0 * m;
 Length y = 3.0 * m; // instead of "m" use "ft";
 cout << "x=" << x << " y=" << y << endl;
 Length z = x + y;
 cout << "x+y=" << z << endl; // display result in "ft"
 return 0;
} // main
Warning: untested code

typedef quanttyus::foot_base_unit::unit_type Length;
Length x(2.0 * m);
