Hi Robin,

I don't know if there is something build in but the following definition
should
work for simple cases.

\def\widthof#1%
  {\bgroup
   \setbox\scratchbox\hbox{#1}%
   \the\wd\scratchbox%
   \egroup}

\starttext

\getrawparameters
  [robin]
  [width=\widthof{Robin Kirkham}]

\robinwidth

\stoptext

Wolfgang
