[Boost-users] boost::units unit proposal

Boost::units developers / users, I need to specify a U.S. Barrel (bbl) for purposes of performing conversions and so forth. First, does this definition look about right? Second, how does one propose an addition to the units code base? Note, I'm not quite sure how the 2^3 scaling from gallon to pints works in terms of scaling from barrel to gallons, or pints for that matter, so I am assuming that gallon can be the base unit for barrel and call it good. Thoughts, questions, concerns? namespace us { typedef scaled_base_unit > barrel_base_unit; } // namespace us template<> struct base_unit_infous::barrel_base_unit { static const char* name() { return("bbl (U.S.)"); } static const char* symbol() { return("bbl"); } }; Thank you...
