Bug in the german translation concerning pound / Pfund
I just checked all the calculators supported by OpenSuSE 15 and this one is my favorite - however, there is one bug reated to the german translation. While its correct that the german word for "pound" is "Pfund", also the weigths differs. One german Pfund is exactly 500 g. The calculator currently uses the weight of the american pound (~453 gramm) when calculating with "Pfund" which is wrong.
A solution would be to support both, a "pound (american)" equalling 453 g and a "Pfund (german)" with 500 g.
