Hello boost-users,

I would like to know if there is an equivalent for giving a name and a symbol given a unit in boost::units (maybe scaled from another one).

I know the example of naming base units, however, it would imply I'd have to create a system and a conversion for every unit I want to implement.

I tried to write it directly from the scaled version, like this:

  template<>                                           
  struct scale_minute<60, static_rational<1> >                      
  {                                                    
      static const long base = 60;                  
      typedef Detail::static_rational<1> exponent;                      
      typedef double value_type;                       
      static value_type value()   { return(60); }    
      static std::string name()   { return("minute"); }  
      static std::string symbol() { return("m"); }
  };

however, it is adding my scaled name plus my base name (say the base name is “s” which stands for seconds, then it would print “m” + "s”).

Any idea how to overcome with that?
