The formula for calculating percentage error is simple:[1]'[(|Exact Value-Approximate Value|)/Exact Value] x 100 The approximate value is the estimated value, and the exact value is the real value. Percentage Error Definition The percentage error, also known as percent error, is a measure of how innaccurate a measurement is, standardized to how large the measurement is.

A measuring instrument shows the length to be 508 feet. What Is A Good Percent Error Since the measurement was made to the nearest tenth, the greatest possible error will be half of one tenth, or 0.05. 2. The percent of error is found by multiplying the relative error by 100%. Kick Images, **Getty Images** By Anne Marie Helmenstine, Ph.D.
