-The author of this package is a physics teacher at the high school \emph{Kantonsschule Zug}, Switzerland. The main use of this package is to write physics problem sets. \LuaLaTeX{} does make it possible to integrate physical calculations directly. The package has been in use since 2016. Many bugs have been found and fixed. Nevertheless it still is possible, that some were not found yet. Therefore the author recommends not to use this package in industry or science. If one does so, it's the responsability of the user to check results for plausability. If the user finds some bugs, they can be reported at github.com or directly to the author (\texttt{thomas.jenni (at) ksz.ch}).

 Very often, the result of a calculation has to be converted to another unit. In listing~\ref{lst:Volume of Cuboid} the task is to calculate the volume of a cuboid. The length of the edges are given in different units. The volume is calculated by multipling all three lengths, the unit of the result is \si{\cm\mm\m}. If the unit \si{\cm\cubed} is preferred, it has to be converted explicitly. The conversion function is called |to()| and is available on all physical quantitiy instances. At first this looks a bit cumbersome. The reason of this behaviour is, that the software is not able to guess the unit of the result. In many cases, like in the example here, it's not clear what unit the result sould have. Therefore the user has always to give the target unit explicitly.

 The package supports uncertainty propagation. To create a number with an uncertainty, an instance of |physical.Number| has to be created, see listing~\ref{lst:rectangular area}.

The first argument of the constructor |N(mean, uncertainty)| is the mean value and the second one the uncertainty of the measurement.
