Just wanted to clarify something. These should convert from given
quantities to the desired units?
If what you really want is a raw double,
than, yes, this should work.
...
double
unit_conversion::from_length_to_inches(quantity<length> const & L) {
                const quantity<inch_base_unit::unit_type> result_(L);
                return result_.value();
            }
double unit_conversion::from_mass_to_pounds(quantity<mass>
const & M) {
Pounds is a unit of force, not mass.  To do
such a conversion, you need to multiply by g.
...
const quantity<ounce_base_unit::unit_type> result_(M);
                return result_.value();
            }
