inter-unit-product is an available option and described in the documentation. To get correct spacing you should use ${}\cdot{}$. However I prefer a tighter spacing by $\cdot$.

\SI[inter-unit-product =$\cdot$]{1.0}{\newton\meter}\\
\SI[inter-unit-product =${}\cdot{}$]{1.0}{\newton\meter}\\

enter image description here

To set his behavior for the whole document you can specify the option via \sisetup

\sisetup{inter-unit-product =$\cdot$}

    I want this setting for whole document.

    @MarcoDaniel One should use \si[inter-unit-product = \ensuremath{{}\cdot{}}] to get the corrected spacing. Commented Apr 10, 2013 at 12:57
  • Setting this behaviour for the whole document directly at the package call is done without the math typesetting $-symbols: \usepackage[inter-unit-product =\cdot]{siunitx}

  • @SvendTveskæg Sorry for being late to the party. Could you explain how one can know what is the "correct" spacing for any situation? I find it hard to try answer some basic questions I have an resort to posting questions here because some people argue that approach B is better than approach A because it have "correct" spacing but I do not know what is the correct spacing for a given situation? Thanks in advance btw

Sorry for the zombie reply, but aren't the units typeset in math mode? In that case:

\SI[inter-unit-product =$\cdot$]{1.0}{\newton\meter}

won't compile. You should use:

\SI[inter-unit-product =\ensuremath{\cdot}]{1.0}{\newton\meter}

    This is already covered in the other answer (to some extent).

  • In the recent siunitx major update from version 2 to version 3, the \SI command has changed to \qty command. And you can still use the old commands, the author says "Where possible, older names are mapped to newer ones internally: you will be warned in the log if this is the case."
