Re: Anyone using the Units package extensively?

Hello,

I've been using an enhanced version package combining units and physical
constants for several years. I started off wanting things like a symbol hbar
that would only turn into the numerical value PlanckConstant when I applied
N to an expression. The latest version includes registration of symbols in a
database that allows you to do automatic dimension checking of expressions.

It can be downloaded from

http://jowett.home.cern.ch/jowett/Accelerator/ConstantsUnits.html

The notebook implementing the package contains examples. The choice of
physical constants is oriented towards the ones used in my field but could
easily be adapted.
