Webbetter referred to as an uncertainty, though the term “error” is in common usage. Precision refers to the size of the uncertainty on a measurement. The absolute precision on a measurement of quantity x is simply the total uncertainty δx. The relative precision is δx/x. Accuracy refers to how close the result is to the “true” value.
