The approach to user input in Revit is analogous to the approach to output.
User may type a specific unit designation i.e. 2", 5m, or 1200mm. User may
even type a formula containing a mixture of units like = 32' 6" + 3m. If
however user does not type the unit indicator then input is interpreted
according to a current setting in Units dialog. User however may change this
setting during a session. This is just the outline of the approach. There
are some special cases for when dealing with very small items like pen
thicknesses but you get the general idea. You may play with Revit
interactively and discover for yourself.

Actually, I believe it is a meaningfull question. How can we find out what
the CURRENT unit type is? if I want to prompt the user to enter a window
size, is he/she going to do it in metric millimeter or foot/inch entry?
This is important...the base level...what will Revit understand is
feet...but what is the user entering?

I don't think this question is meaningful for Revit. Internally Revit stores
all coordinates in universal units (feet) regardless of geography or
localization considerations. Revit just displays dimension according to user
preferences. Thus the same rvt file may show some dimensions as imperial and
others as metric. This also allows loading imperial families into project
that is dimensioned in metric or the other way around. It works differently
from Autocad.

How can I find the whether the drawing is a Metric or Imperial drawing. And
if metric, whether the base units are set to Millimeters or something else.
Thanks
