Enter the length and width in pixels of the camera, photo, screen, or tv into the calculator to determine the total number of megapixels.

## Megapixel Formula

The following formula is used to calculate the number of megapixels in a given screen, tv, camera, or photo.

MP = L * W / 1,000,000

- Where MP is the number of mega pixels
- L is the length in pixels
- W is the width in pixels

## Megapixel Definition

**What is a megapixel? **

A megapixel is defined as a unit that is equal to 1 million pixels.

**What is a pixel? **

A pixel is the smallest addressable element in a picture or screen. An addressable element means that the element can be affected or changed.

## Example Problem

How to calculate a megapixel?

**First, determine the number of pixels along the length of the screen.**For this example, we are looking at a screen with a resolution of 1920 pixels along the length.

**Next, determine the number of pixels along the width.**In this case, the screen has a standard resolution of 1080 along the width.

**Finally, calculate the number of megapixels using the formula.**Using the formula above, the number of megapixels is calculated as:

MP = L * W / 1,000,000

MP = 1920 * 1080 / 1,000,000

MP = 2.0736
