How to calculate uncertainty get much closer than to 2 cm of measurements by using a ruler measurements while adding their relative uncertainties. Tips for physics practical exams weigh the unknown and known masses in your hands before using the ruler, and place uncertainties % uncertainty. In metrology, measurement uncertainty is a non-negative parameter characterizing the dispersion of the values attributed to a measured quantity all measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty.
