The problem is that the PCB libraries are created in mil in the
headquarter in Germany and the local SMD machines and board
houses are using mm. Some of the old documentation are also
using mil but we are woking with mm now so we need to
translate mil to mm. What I am saying is that we need to convert
100 mil to 2.54mm and not 2.5mm.
