I want to change the pix distance of the image with Millimeter.
In other words, what is the conversion from a pix length to millimeter?
Thank you for you help!

It is 42. Seriously, you need to put an object of known length into your image and measure its length in pixels. Then you can have a spatial calibration factor that you can use to multiply your lengths in pixels by to get your length in mm.
