It may be worth mentioning that you can choose the document units that you prefer when you start up Inkscape. If you use the startup template file C:\Program Files (x86)\Inkscape\share\templates\default.svg (which is the default), then you will find that the document units are mm. You can confirm this by drawing a rectangle that has the width of the full page and then using the XML editor to confirm that the width has been expressed in mm. A typical example would be
<rect style="..." id="rect10" width="210.91072" (should be 210, my hand was shaky) height="88.446426" x="0" y="0.66666663" />
If you prefer to use px as the document units, then use the template file C:\Program Files (x86)\Inkscape\share\templates\default_px.svg. In this case if you draw a rectangle that has the full width of an A4 page you will get:
<rect style="..." id="rect18" width="797.14288" (should be 793.7007, which is 210mm expressed in px) height="357.14285" x="0" y="2.519685" />
If you prefer to use pt as document units, then use the template file default_pt.svg
If you want to permanently modify the startup units, then copy a file like default_pt.svg to overwrite the file default.svg. (after first making a backup, just in case.)
The one thing you cannot do, however, is modify the document units after Inkscape has opened the startup file.
