1. Setting a dimension isn't expandable, so you need to do that before
using \unit.
2. You need to make sure that the argument to \unit is expanded before
\unit itself is.
The following should work as expected:
\mainlanguage[de]
\setupunit[method=3,space=small,]
\define[2]\Conv{%
\scratchdimen=#1
\normalexpanded{\noexpand\unit{\the\nodimen #2 \scratchdimen}}
}
\starttext
\bTABLE
\bTR\bTH Einheit \eTH\bTH mm \eTH\bTH pt \eTH\eTR
\bTR\bTD 1 dk \eTD\bTD \Conv{1dk}{mm} \eTD\bTD \Conv{1dk}{pt} \eTD\eTR
\bTR\bTD 1 es \eTD\bTD \Conv{1es}{mm} \eTD\bTD \Conv{1es}{pt} \eTD\eTR
\bTR\bTD 1 ts \eTD\bTD \Conv{1ts}{mm} \eTD\bTD \Conv{1ts}{pt} \eTD\eTR
\eTABLE
\stoptext
