Percent Error Calculator
This Percent Error Calculator (% error calculator) will calculate the percentage error between an experimental measured value and a theoretical actual value.
Percentage Error Formula
Where E is the experimental value and T is the theoretical value. This formula is similar to percentage change.
For example, how to calculate the percentage error:
Suppose you did an experiment to measure the boiling point of water and your results average to 101.5°C. This is your experimental (measured) value. We know that the actual boiling point of water is 100°C, so this is your theoretical (actual) value. What is the % error between E = 101.5°C and T = 100°C?
