The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π. Normally people use absolute error, relative error, and percent error to represent such discrepancy: absolute error = |Vtrue - Vused| relative error = |(Vtrue - Vused)/Vtrue| http://maxspywareremover.com/percent-error/what-is-the-percent-error-calculation-used-to-determine.php
