How do you oblicz percent error?

Percent error = |measured − actual| / |actual| × 100. If you measured 9.80 and the true value is 9.81, the percent error is about 0.10%.

What's the difference between absolute and relative error?

Absolute error is the raw difference |measured − actual|. Relative error divides that by the true value; multiply by 100 for percent error.
