Pixels to Megapixels Explained:

While converting pixels to megapixels it might not seem as important as changing inches to centimeters, but it can be vital, especially if you are doing any photography work or comparing one camera to another one.

Essentially one megapixel is the same as 1,000,000 pixels.

To work out how many megapixel something has you just need to multiply the horizontal pixels by the vertical pixels and see what you get.

So, something that has a resolution of 640×480 pixels has the equivalent resolution of 0.3 megapixels.

640×480 = 307,200 pixels

And something that has a resolution of 1280×1024 pixels has an equivalent resolution of 1.3 megapixels.

1280×1024 = 1,310,720 pixels

A good tip to remember is that when comparing cameras, you should compare the native resolution of the camera and not the software interpolated resolution of the camera.

If you follow these tips you’ll be happy dealing with any measurement in no time at all.
