Definition: Relative uncertainty is a measure of the uncertainty of measurement compared to the size of the measurement. Also Known As: relative error. Examples: Three weights are measured at 1.05 g, 1.00 g, and 0.95 g. The absolute error is Â± 0.05 g. The relative error is 0.05 g/1.00 g = 0.05 or 5%.
