Three comments, from looking at it: - "physical", not "phisical" ;-) - you raise string exceptions in various places; these are deprecated and should not be used. Also it is very difficult to catch them. - ScientificPython from Konrad Hinsen also contains a somewhat similar module. IIRC, it is named PhysicalQuantities. You might look into that and mention it on the homepage. Thomas -- http://mail.python.org/mailman/listinfo/python-list
