Here is how to calculate percent error, with an example calculation.Percent Error FormulaFor many applications, percent error is expressed as a positive value. Calculate the percent error of your measurement.Subtract one value from the other:2.68 - 2.70 = -0.02 Depending on what you need, you may discard any negative sign (take the absolute value): 0.02This Enter Actual Value - This is the theoretical, known, true, correct, accepted or exact value.

The order does not matter if you are dropping the sign, but you subtract the theoretical value from the experimental value if you are keeping negative signs. And we can use Percentage Error to estimate the possible error when measuring. Comparing Approximate to Exact "Error": Subtract Approximate value from Exact value. The absolute value of a negative number will turn it positive.

It is often used in science to report the difference between experimental values and expected values.The formula for calculating percent error is:Note: occasionally, it is useful to know if the error You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3.

Whether error is positive or negative is important.

Find what percent is a number out of a second number? The relative error is calculated as the absolute error divided by the magnitude of the exact value. For example, you would not expect to have positive percent error comparing actual to theoretical yield in a chemical reaction.[experimental value - theoretical value] / theoretical value x 100%Percent Error Calculation Hours and minutes calculators.

Quickly calculate percent error, use Percent Error Calculator. A small error means the measured value is close to the actual value.
