The point of my question was: can I feed the content of tex.dimen["textwidth"] directly back to TeX, and the answer to this appears to be "no"; you need to add some unit to it (otherwise, you get an error message). Which was a bit confusing to me at first, because the name tex.dimen implies that it holds a "real" dimension, like \newdim does.


You can get the same value in TeX when you print the value of a dimension with \number:

\starttext

\scratchdimen=3pt

\number\scratchdimen

\ctxlua{context(tex.dimen["scratchdimen"])}

\stoptext
