How do you get percent error?

Answer:
The definition of error is: difference between the accepted true value and the measured value of a quantity or parameter. But this is the absolute error.

The relative (percent error) is:

(measured value - accepted true value) . 100/accepted true value

This value is exprssed as a percentage - %.
