convert to mm

I down loaded some files of the internet there in inches and there very small in z suits, I don't remember

how to convert it back the the right scale ? thanks for your help

When I see this probably I scale all three axes by 25.4 and that usually brings them to the expected size.  My assumption is that the STL file was created with dimensions in inches, whereas Zortrax apparently expects STL files to have units of mm.  If so then Zortrax sees a 1-in x 1-in x 1-in cube as 1 mm x 1 mm x 1 mm.  1 inch = 25.4 mm.
