Calculate measurement accuracy. Compares experimental outcomes against accepted theoretical constants to evaluate percentage deviation.
How to use
- Input the accepted theoretical value (Accepted/Theoretical).
- Enter the measured experimental value (Measured/Experimental).
- Review the computed percent error (%) and view the accuracy grade guidelines.
FAQ
- Can percent error be negative?
- No. The percent error formula uses the absolute difference between theoretical and experimental values, meaning the result is always positive.
