What is Percent Error Calculator?

The Percent Error Calculator is a tool designed to help users determine the accuracy of an experimental measurement compared to its theoretical (true) value. By entering the experimental and theoretical values, the calculator instantly computes the percent error, showing how close the measurement is to the expected result. This tool is useful for students, scientists, and engineers who want to analyze experimental results, validate data, and understand measurement accuracy.

How to Use:

1. Enter Experimental Value: Type the value you measured in your experiment.
2. Enter Theoretical (True) Value: Input the known or accepted true value.
3. Click “Calculate”: The calculator computes the percent error instantly.
4. Review the Result: The output displays the percent error, helping you evaluate measurement accuracy and compare results effectively.
