Step 1
Accuracy of a measured value refers to how close the measurement is to the correct value. The uncertainty in a measurement is an estimate of the amount by which the measurement result may differ from this value.
Step 2
Generally, uncertainty is given as a percentage. The uncertainty of a measurement is related to the degree of accuracy of the experimental results. In other words, the uncertainty depends on how accurate is an experimental measurement. A high accuracy of an experimental result can be traduced as a lower value of uncertainty and vice versa.
