It is imported with one unit per pixel. So for instance an image of 900x600 pixels will be in a drawing with meter set as unit ( edit - current drawing -units ) 900x600 meters. If you know with what dpi the image was scanned you can calculate the scaling factor you have to apply after importing. Or if you know an the real live size of something in the image, you can measure that in the drawing ( info - distance point to point ) and then calculate the necessary scaling factor to get it to the right size.
