Calculate the relative error, absolute error, and percentage error effortlessly. Our free online calculator helps you assess the precision and accuracy of your measurements, experiments, and data. Quickly determine the deviation from the true or accepted value with this essential scientific and mathematical tool.
Formula:
Absolute Error (AE) = |Measured Value - True Value|
Relative Error (RE) = AE / |True Value|
Percentage Error (PE) = RE × 100%
Where:
- Measured Value (MV): The observed or experimental value.
- True Value (TV): The accepted, actual, or theoretical value.
- AE: Absolute Error.
- RE: Relative Error.
- PE: Percentage Error.
