Percent Error Calculator
Calculate the percentage difference between theoretical and experimental values.
Understanding Percent Error
Percent error measures the accuracy of an experimental value compared to its theoretical (expected) value. It's commonly used in scientific experiments, engineering measurements, and quality control.
Formula
The percent error formula is:
Percent Error = |Theoretical - Experimental| / |Theoretical| × 100%
Common Applications
- Laboratory measurements and scientific experiments
- Manufacturing quality control
- Engineering tolerance analysis
- Educational assessment of experimental accuracy
Tips for Reducing Percent Error
- Use calibrated measuring instruments
- Take multiple measurements and average the results
- Control environmental conditions
- Follow proper experimental procedures
