Percentage Error Calculator
Calculate the percent error between an experimental value and a theoretical (actual) value.
Percentage Error
2.0000%
Absolute Error: 0.2000
Σ The Formula
% Error = (|Experimental - Theoretical| / Theoretical) × 100
Real World Examples
Chemistry Lab
Yield was 9.8g, Expected 10g = 2% Error.
Measurement
Measured 102cm, True length 100cm = 2% Error.
# About This Calculator
Percentage Error is a common metric in science and engineering to express how accurate a measured value is relative to the true or accepted value.
