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?

1. 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.

2. Next, determine the number of pixels along the width.

In this case, the screen has a standard resolution of 1080 along the width.

3. 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
