I got from a website some gerber files, I tried to have them printed, but they told me that the format is not supported and I need to convert to RS-274X.
I've tried using gerbv to open the gerbers and export to the 274x format, but after opening it still complains about some being 274d.
So I've tried a commercial application (gerbview), but which managed to convert them but totally screwed up the scaling and ended up with a 1mm wide PCB.
On last resort, I've manually edited the files with a text editor and manually changed the scale of every piece and I've to say KiCAD renders it correctly, but any other viewer (gerbv and the one used by the pcb printing website) does not and still show the scaled down layout.
EDIT: as suggested, here is the link to the origianl files I want to convert
