If I reconstruction a 10cm^3 cube, will the output 3D model be the same size as the real world? Or is there a certain conversion ratio?

I think there is no real size, but I'm not sure. For size precision use photogrammetry or LIDAR technology. I can recommend Reality Capture as it's free for normal users. But I'm not completely sure.
