In most cases we want conversions between systems and that is why nearly all
systems provided with this library are implemented in terms on the :term:`SI`

In case we would like to print the result in terms of base units we can simply do the
following::
auto s = quantity_cast<unknown_coherent_unit>(result);
auto s = quantity_cast<decltype(result)::dimension::coherent_unit>(result);
std::cout << "Speed: " << s << '\n'; // prints 'Speed: 20 m/s'
