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?

try: #include using minutes = boost::units::metric::minute_base_unit::unit_type;

You should be able to use the same method of specializing base_unit_info.

Please notice minute was just a very dumb example to illustrate the idea. Santiago
