Introduction: Percent Error Calculator

The Percent Error Calculator is a valuable tool for students, educators, and professionals who deal with measurements and data comparisons. Whether you’re conducting a science experiment, verifying mathematical results, or analyzing discrepancies between expected and actual outcomes, calculating the percent error is essential for understanding the accuracy of your findings.

This easy-to-use calculator helps you determine the percentage difference between an observed (measured) value and the true (actual) value. By inputting these two values, the tool instantly computes the percent error using the standard formula:

Percent Error = [(Measured – Actual) / Actual] × 100

Understanding percent error is crucial in fields such as chemistry, physics, mathematics, and engineering. It allows users to quantify how far off their measurement or estimate is from the true value, helping improve accuracy and precision in calculations and experiments.

Our calculator simplifies the entire process, removing the need for manual formulas or spreadsheets. Whether you’re a high school student in a lab or a professional analyzing data, this tool saves time and ensures accurate results.
