Megapixel Calculator - digital camera resolution

Purpose

This is a megapixel calculator, a tool to calculate and convert graphical resolution, image memory consumption and file sizes. How many pixels in a DVD image? How does that compare to a 5 megapixel camera? What is the resolution of Digital Cinema 2K? The answer is here!
