Pixel to Centimeter?

Question

I just want to know if the pixel unit is something that doesn\'t change, and if we can convert from pixels to let\'s say centimeters ?

Answer 1

You can convert from pixels to centimeters, but it's not a consistent conversion. It will depend on the size and resolution of the display device in question. The definition of a pixel will not change, but the size of a pixel will vary on different display devices.
