You can use \measured or just create more named lengths.

\definemeasure [onemeasure] [4cm]
\definemeasure [twomeasure] [\measure{onemeasure}*2]
%\definemeasure [twomeasure] [2\measured{onemeasure}]

\starttext
   \framed[width=\measure{onemeasure}]{Foobar}
   \framed[width=2\measured{onemeasure}]{Foobar}
   \framed[width=\measure{twomeasure}]{Foobar}
\stoptext
