Math Calculators
Percent Error Calculator
Calculate percent error, absolute error, and relative error between experimental and theoretical values.
What is the Percent Error Calculator & How does it work?
Percent Error Calculator helps determine the discrepancy between an observed value (experimental) and a true or expected value (theoretical). This tool is essential in scientific experiments to assess the accuracy of measurements. The percent error provides a percentage representation of this difference, making it easier to understand the magnitude of the error relative to the theoretical value.The absolute error is simply the difference between the experimental and theoretical values without considering their signs, while the relative error expresses this difference as a fraction or ratio of the theoretical value. These metrics collectively offer insights into the precision and reliability of experimental data.
\text{Percent Error} = \left( \frac{|E – T|}{T} \right) \times 100\%
E = Experimental Value, T = Theoretical Value
