Percent Error Formula
Percent Error is the difference between the true value and the estimate divided by the true value and the result is multiplied by 100 to make it a percentage. The percent error obviously can be positive or negative; however, some prefer taking the absolute value of the difference.The formula is the absolute value of the experimental value (minus) the theoretical value divided by theoretical value times 100.
% error = (|Your Result - Accepted Value| / Accepted Value) x 100
