Percent error is used to show how far an experimental
value is from an actual or expected value.

Percent error can be found using the formula below.

% error = \frac{| experimental - actual |}{actual} \times 100

\begin{array}{rcl} % error & = & \frac{| experimental - actual |}{actual} \times 100 \\ = & \frac{| 0.43 - 0.5 |}{0.5} \times 100 \\ = & \frac{| - 0.07 |}{0.5} \times 100 \\ = & \frac{0.07}{0.5} \times 100 \\ = & 14 % \end{array}
