Joel, A quantitative units library has been accepted into Boost. My guess is that it is slated to release with 1.35. The announcement can be seen here: http://lists.boost.org/boost-announce/2007/04/0126.php In addition, another library of similar purpose was proposed for inclusion into Boost. It was rejected at the time, and it now maintains its lifecycle on Sourceforge. If I recall correctly, this library is called "Quan", and the project page can be found here: http://sourceforge.net/projects/quan/ This is a topic I try to follow, as I am really looking forward to the inclusion of such a library into Boost. You can see the review schedule, along with the libraries that have been accepted or rejected at the following location: http://boost.org/more/formal_review_schedule.html Justin On Sunday 07 October 2007 12:18:11 Joel C.

Have the dimensional analysis templates suggested in <http://www.boost.org/libs/mpl/doc/tutorial/dimensional-analysis.html> ever been developed into readily usable form?
