Setting all defaults as millimetres???

Hi all,

Due to the fact that most of my components are relatively small and that I live in Australia where the metric system is used, is there a way to set 'smart dimension' to millimetres (mm) as a unit of measure by default so that I don't have to type in the "mm" every time I use it? Or even better still, set ALL of SolidWorks to millimetres by default????

Dave.
