Did this article help you? Since the experimental value is smaller than the accepted value it should be a negative error. The error in measurement is a mathematical way to show the uncertainty in the measurement. Wird verarbeitet...

When the accepted or true measurement is known, the relative error is found using which is considered to be a measure of accuracy. Accuracy is a measure of how close the result of the measurement comes to the "true", "actual", or "accepted" value. (How close is your answer to the accepted value?)

Greatest Possible Error: Because no measurement is exact, measurements are always made to the "nearest something", whether it is stated or not. To determine the tolerance interval in a measurement, add and subtract one-half of the precision of the measuring instrument to the measurement.

While both situations show an absolute error of 1 cm., the relevance of the error is very different.
