Percent error measures the accuracy of an experimental or measured value compared to an accepted or theoretical value. It expresses the discrepancy as a percentage, making it easy to compare errors across different scales and units.

Schritt-für-Schritt-Anleitung

  1. 1Percent error = |Experimental − Theoretical| / |Theoretical| × 100%
  2. 2The absolute value removes the sign — percent error is always positive
  3. 3Signed percent error indicates direction: positive = measured too high, negative = too low
  4. 4Used in chemistry, physics, engineering, and manufacturing quality control

Eingabe
Measured density: 9.7 g/cm³, True density: 10.0 g/cm³
Ergebnis
3.0% error
|9.7−10| / 10 × 100 = 3%
Eingabe
Predicted 50, actual 47
Ergebnis
6.0% error
|50−47| / 47 × 100 = 6.38%
