Some facts#
 Absolute error is the absolute value of the difference between measured value (calculated, approximate etc.) and reference value (ideal, theoretical etc.):
$\Delta x = xx_0$where:
 $\Delta x$  absolute error,
 $x$  measured, calculated or approximate value of variable $x$,
 $x_0$  the reference value against which we calculate the error.
 $\Delta x$  absolute error,
 Relative error determines the size of the error made presented as part of the reference value:
$\delta x_{wzgl.} = \left\dfrac{xx_0}{x_0}\right$where:
 $\delta x_{rel.}$  error expressed as a part of the reference value,
 $x$  measured, calculated or approximate value of variable $x$,
 $x_0$  the reference value against which we calculate the error.
 $\delta x_{rel.}$  error expressed as a part of the reference value,
 When we determine the error, we are generally not trying to find out whether the value obtained is too large or too small, but only how big the error is. This is the reason why error formula has the absolute value form.
 In the case of values with units (e.g. length measured in meters), the absolute error has the same units as the measured one. For example, an absolute error of length value is also the length.
 Relative error has no units, no metter what do we measure. Relative error is often presented as percent.
