How to Calculate Here is the way to calculate a percentage error: Step 1: Calculate the error (subtract one value form the other) ignore any minus sign. Step 2: Divide the error by the exact value (we get a decimal number) Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) As Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of Source(s): calculate percent error chemistry: https://tr.im/WELfU ? · 1 year ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse For the best answers,
