Pixel i.e. "the smallest controllable element of a picture represented on the screen". For example, if you had a picture where Neptune was 1000 pixels in radius, and one of its moons was (say) 10 pixels, you could use the knowledge that Neptune's radius is 24,622 km to say that the scale for the picture is 24,622 meters. From there, you could apply that scale to Neptune's moon to show that its radius is 246,220 meters.

It doesn't work as well for stuff like cutscenes and gameplay footage, because the developers make the objects in it whatever size they feel is "right", not according to a clear scale. (Also, it makes my 6.62e39 J result for DK's moon punch go up to 3e43 J.)
