Ok. That makes Length represent "feet" But I want Length to remain represented as an si::length, but input "ft" into it and convert to "ft" to print.
// static const si::length ft = ???; typedef quantity<si::length> Length; Length x = 3.0 * ft; cout << "x=" << convert_to_ft(x) << endl;
typedef quantity<us::foot_base_unit::unit_type> convert_to_ft;
Got it! Now the other part... typedef quantity<si::length> Length; Length x = 3.0 * ft; If x is an SI unit, how can I convert from "ft"? I'm missing something, but I'm not sure what. terry
