Percentage Error Calculator: Measure Accuracy with Ease
When working with experiments, measurements, or data analysis, accuracy is everything. A Percentage Error Calculator helps you determine how close your observed results are to the actual or true value. This tool saves time and ensures precision by automatically computing the percentage error in just a few steps.
What Is Percentage Error?
Percentage error is a way to measure how far off your observed value is from the true value. It is commonly used in science, engineering, and education to evaluate the reliability of results.
The formula is:
Percentage Error = ((Observed Value – True Value) ÷ True Value) × 100
This calculation shows the error as a percentage, making it easier to interpret and compare results.
