Another way is to use the string library from lua to replace μμ with mm:
\unprotected\def\interfaceddimension#1%
{\ctxlua{commands.interfaceddimension(\!!bs\detokenize{#1}\!!es)}}
\startluacode
function commands.interfaceddimension(str)
if string.match(str,"\\") then
-- dimension or macro
else
str = string.gsub(str,"μμ","mm")
end
tex.print(str)
end
\stopluacode
\setupbodyfont[palatino]
\starttext
\def\foo{4mm}
\def\bar{\textwidth}
\scratchdimen\interfaceddimension{2mm} 2mm: \the\scratchdimen\crlf
\scratchdimen\interfaceddimension{1μμ} 1μμ: \the\scratchdimen\crlf
\scratchdimen\interfaceddimension\foo foo: \the\scratchdimen\crlf
\scratchdimen\interfaceddimension\bar bar: \the\scratchdimen
\stoptext
