How can I print a length of hsize (Horizontal size) in mm (millimeter)?

Question

I am new to VTEX. How can i solve this??

\documentclass{article}
\begin{document}
\the\hsize
\end{document}

Output: 345.0 pt

but i have to write a macro to calculate hsize in mm example: \printdimen[mm]\hsize and if i take hsize 6.5in then what will be output in mm?

You've already asked two questions in this area, and have answers on the previous one that cover this (http://tex.stackexchange.com/questions/239647/how-can-i-print-a-length-in-centimeters-in-vtex). Closure as a dupe of your existing question is likely unless you can make a case for this one being distinct. — Joseph Wright, Apr 21 '15 at 15:13

Like this?

\documentclass{article}
\usepackage{printlen}
\begin{document}
\uselengthunit{mm}\printlength{\hsize}
\end{document}

@jon no idea, what that is. Sorry. – LaRiFaRi Apr 21 '15 at 14:50
No e-TeX extensions. – jon Apr 21 '15 at 14:53
@LaRiFaRi i want to show output only 121.25221 mm. In that case what i have to do? whenever i use \printdimen[mm]\hsize then output ll be only 21.25221 mm "Thanks" – enadul shaheen Apr 21 '15 at 16:12
@enadulshaheen you get 21... when compiling my MWE? – LaRiFaRi Apr 21 '15 at 16:17
@LaRiFaRi sorry it should be 121.25221 mm (not 21.25221). I mean when i will write \printdimen[mm]\hsize then output will be only 121.25221 mm. Thats all. "Thanks" – enadul shaheen Apr 21 '15 at 16:39
@enadulshaheen sorry, I don't get it. The output of my macro is exactly what you desire. – LaRiFaRi Apr 21 '15 at 17:35
