The relative error expresses the "relative size of the error" of the measurement in relation to the measurement itself. http://back2cloud.com/percentage-error/percentage-error-of-equipment.php

When the accepted or true **measurement is known, the** relative error is found using which is considered to be a measure of accuracy. Example Calculations 13 mm was the smallest length measured 1 mm the uncertainty % Equipment Error = uncertainty x 100 / amount measured = 1 mm x 100 / 13 = hope it helps.

Uncertainty Of Measuring Cylinder Time is something where you have to take into account your reaction time...i think the best uncertainty for time is about ± 0.5s because thats how long it takes to react..

Absolute Error: Absolute error is simply the amount of physical error in a measurement. More about the author Neil the seal 1 Contribution Improved Answer In Numerical Analysis and Simulation How do you calculate percentage error? Some measurement uncertainties are given below: EquipmentMeasurement to the nearest: Balance (1 decimal place)0.08 g Balance (2 decimal place)0.008 g Balance (3 decimal place)0.0008 g Measuring Cylinder (25 cm3)0.5 cm3 Graduated The way I calculated the percentage error for the appartus is by the following formula: Percentage = Error Uncertainty / Reading x 100 The typical uncertainties for the equipment you mentioned Calculating Percentage Error Chemistry Titration
