Take a look at:
http://home.tiscali.be/be052320/Unum_tutorial.html

 From the intro:

"Unum stands for 'unit-numbers'. It is a Python module that allows to define and 
manipulate true quantities, i.e. numbers with units such as 60 seconds, 500 
watts, 42 miles-per-hour, 100 kg per square meter, 14400 bits per second, 30 
dollars etc. The module validates unit consistency in arithmetic expressions; it 
provides also automatic conversion and output formatting."
