You have to use the \measured (with a trailing s) command when you need
multiples of a measure value. When you use something like 2\measure{...}
ConTeXt uses the "2" followed by the value of the measure, the following
example demonstrates this in the second output.

%%%% begin example
\definemeasure [point] [1pt]

\starttext

\startbuffer
\tex{measure}: \measure{point}

\tex{measured}: \the\measured{point}
\stopbuffer

\typebuffer \getbuffer

\startbuffer
2\tex{measure}: 2\measure{point}

2\tex{measured}: \the\dimexpr2\measured{point}\relax
\stopbuffer

\typebuffer \getbuffer

\stoptext
%%%% end example
