What is Percent Error?

Percent Error is a measure of how accurate a measurement is compared to the accepted or true value. It is calculated by taking the difference between the measured value and the accepted value, then dividing it by the accepted value and multiplying it by 100. This gives you the percentage of error in the measurement.

What is Percent Error Calculator?

A Percent Error Calculator is a tool used to calculate the percentage of error between an observed value and the true value of a measurement. It is used to measure the accuracy of a measurement and is calculated by dividing the difference between the observed value and the true value by the true value, then multiplying the result by 100.

How to Calculate Percent Error?

To calculate percent error, take the absolute value of the difference between the experimental value and the accepted value, divide by the accepted value, and multiply by 100. For example, if the accepted value is 10 and the experimental value is 8, the absolute value of the difference is 2. The percent error is then (2/10)*100 = 20%.
