WebBoth ends of the ruler have a ±0.5 scale division uncertainty, therefore the measurement will have an overall uncertainty of ±1 division. For most rulers, the uncertainty in a measurement of length will be ±1 mm. Summary • The uncertainty of a reading (one judgement) is at least ±0.5 of the smallest scale reading . http://denethor.wlu.ca/pc131/uncbeam_div.pdf
