Percent Error Calculator

The Percent Error Calculator is a simple tool used to determine the accuracy of a measured or experimental value compared to a known or theoretical (true) value. It calculates the percentage difference between the two values.

Calculation Method formula:

Measured Value = The observed or experimental result.
True Value = The accepted, expected, or theoretical value.
Absolute Value (| |) ensures the result is always positive.

How to Use the Calculator
Enter the True Value – The known or expected value (e.g., standard reference).
Enter the Measured Value – The value obtained from an experiment or measurement.
Calculate – The tool will compute the percent error automatically.
Interpret the Result – A lower percent error indicates higher accuracy.
