Percent Error Calculator
What is Percent Error Calculator?
The Percent Error Calculator is a professional scientific tool designed to compute percentage error between experimental and theoretical values with comprehensive mathematical analysis and step-by-step solutions.
This tool is essential for scientists, researchers, students, and professionals who need to assess the accuracy of measurements and validate experimental results against known theoretical values.
How is it Calculated?
Percent error is calculated using different formulas depending on the type of error analysis needed:
Percent Error Formula:
% Error = |Experimental - Theoretical| / |Theoretical| × 100%
Where Experimental is the measured value and Theoretical is the accepted value.
Absolute Error Formula:
Absolute Error = |Experimental - Theoretical|
The absolute difference between measured and accepted values.
Relative Error Formula:
Relative Error = |Experimental - Theoretical| / |Theoretical|
The ratio of absolute error to the theoretical value.
Accuracy Formula:
Accuracy = 100% - |% Error|
The percentage accuracy of the measurement.
