Answer by  chirpynits (72)

Percent Error is the difference between the true value and the estimate divided by the true value and the result is multiplied by 100. The percent error can be either positive or negative. Hence, Percentage Error can be stated in formula as follows: % error = (|Value received - Theoretical Value| / Theoretical Value) x 100

Answer by  willard (874)

The percentage error is given by the expression below percent error = 100 times (measured value - expected value)/(expected value) So, for example, if you expect 10 and measure 9, the percent error is 100 times (9-10)/10 =-10 percent.
