For example, if you know a length is 3.535 m + 0.004 m, then 0.004 m is an absolute error. Normally people use absolute error, relative error, and percent error to represent such discrepancy: absolute error = |Vtrue - Vused| relative error = |(Vtrue - Vused)/Vtrue| c.) the percentage error in the measured length of the field Answer: a.) The absolute error in the length of the field is 8 feet.
