Is there a way in the iPhone SDK to calculate the size (in millimeters) of a single pixel?
Well, the size of a pixel is a constant. The screen size of a current iPhone or iPod touch 2′ x 3′ (50.8 mm x 76.2 mm) and the resolution is 320 x 480 pixel.
50.8 / 320 (or 76.2 / 480) => the size of 1 pixel is 0.15875 mm x 0.15875 mm
