Classof2013 Posted June 18, 2011 Report Share Posted June 18, 2011 I don't know about where you live, but every ruler here in Canada has millimeters on one side, and centimeters on the other side. Also, this is called a metric ruler since millimeters are of the metric units of measurement. Reply Link to post Share on other sites More sharing options...
Rigel Posted June 18, 2011 Report Share Posted June 18, 2011 You could use a vernier.. I don't know if it would work in your case though. Reply Link to post Share on other sites More sharing options...

Proletariat Posted June 25, 2011 Report Share Posted June 25, 2011 If this is for a lab, then you'll be expected to put uncertainties anyways. Writing "Ruler (+- 0.5mm)" should cover it. Reply Link to post Share on other sites More sharing options...
