[SciPy-user] Units in SciPy

Hi all,

We have been using the units package written by Michael Aivaziz which is 
available here:


One potential issue is that a units package has to guess whether the 
user wants to convert a temperature gradient or a temperature:

1Celsius = 1Kelvin    (gradient)
1Celsius = 274.15Kelvin (absolute)

For a proprietary project Enthought reworked Michael's package to assume 
temperatures are absolute. This is maybe less surprising to a regular 
user but was tantamount to forking Michael's project. It also leaves the 
inherent ambiguity unresolved. If we put Mike's work into scipy we would 
probably want to use it unchanged.

So my questions are:

1) any interest out there in us putting a units package into scipy?
2) any preference for a particular implementation? Unum, etc.
3) does anyone have input or suggestions regarding the temperature issue?
