Well, here is an other explanation for your post.

The factor you've referenced, is a conversion factor, 1mm = 0.0393701 Inch.

Thus the problem lies somewhere in unit conversion.
To see, if this is a LibreCAD issue, we should know, if the original file was created by LibreCAD or any other CAD software. Do you still have the original DXF file and can you share it for investigation?

This factor makes sense, if a drawing was created in 1mm per unit, but the dimension should be in Inch. Whether this makes sense or not, but it works.
