Frequently Asked Questions (FAQ)
What is the Percent Error, Absolute & Relative Error Calculator and how does it work?
Essential physics and chemistry laboratory tool. Compares experimental value $v_{exp}$ to accepted theoretical value $v_{teor}$, calculating $\text{\% Error} = \left| \frac{v_{exp} - v_{teor}}{v_{teor}} \right| \times 100\%$.
How do I use this Percent Error, Absolute & Relative Error Calculator?
Enter Experimental / Observed Value ($v_{exp}$). Enter Theoretical / Accepted Value ($v_{teor}$). View calculated Percent Error, Absolute Error, and Relative Error.
What mathematical formula is used in this calculation?
Absolute Error = |v_exp - v_teor|. Relative Error = |v_exp - v_teor| / |v_teor|. Percent Error = Relative Error * 100%.
