The \setupinterlinspace accepts also numbers to choose a multiple of the 
default distance or you pass a dimension where you set a fixed value for 
the distance between the baselines.

%%%% begin example
\showgrid

\starttext

\samplefile{lorem}

\page

\start \setupinterlinespace[2]% 2 lines, also possible: 1.5, 3, ...
\samplefile{lorem}\par
\stop

\page

\start \setupinterlinespace[line=5.6ex]% also possible: 
\setupinterlinespace[5.6ex]
\samplefile{lorem}\par
\stop

\stoptext
%%%% end example
