My current vision is that Boost.NumericConversion and Boost.Units will provide a support layer for Boost.Convert (let's call it that way for now). That support layer will be implemented as a regular extension for the Boost.Convert library. So, the "convert" function will eventually call numeric_cast or quantity_cast, or any other appropriate tool in these libraries to fulfill the conversion.
There is no function called quantity_cast, in the released version of Boost.Units--it's spelled static_cast. The problem with a fully generic convert is that it's a different beast from string conversions. Converting to and from a string can require formatting information that is meaningless for other conversions and which cannot easily be provided by fully generic code. In Christ, Steven Watanabe
