STRUCT TEMPL(3)

NAME
boost::units::conversion_helper

SYNOPSIS

// In header: <boost/units/conversion.hpp>
template<typename From, typename To>
struct conversion_helper {
  // public static functions
  static To convert(const From &);
};

DESCRIPTION

Template for defining conversions between quantities. This template should be specialized for every quantity that allows conversions. For example, if you have a two units called pair and dozen you would write

     namespace boost {
     namespace units {
     template<class T0, class T1>
     struct conversion_helper<quantity<dozen, T0>, quantity<pair, T1> >
     {
         static quantity<pair, T1> convert(const quantity<dozen, T0>& source)
         {
             return(quantity<pair, T1>::from_value(6 * source.value()));
         }
     };
     }
     }

In most cases, the predefined specializations for unit and absolute should be sufficient, so users should rarely need to use this.
