What is a Percent Error Calculator?

The exact definition of a percent error calculator is measuring two different readings and calculating the correct percent error based on your project. Our website "" is a perfect match tool that helps users define and get the correct answer.

How to Calculate Percent Error?

When we measure any reading of an object by measuring instrument, we usually find the observed value (estimated measured value), which is different from the true value (theoretical actual value). Hence we apply the percent error formula to calculate the correct answers. Read more to know about percent error calculator.

The Simple Formula to Calculate the Percent Error

Percent Error = [(Observed Value - True Value) / True Value] × 100

Now, let's learn how to use "" with the following example.
