1. What is a Pixel to Megapixel Calculator?

Definition: This calculator converts pixel dimensions of an image to megapixels, which is a common measurement for digital camera resolution.

Purpose: It helps photographers, designers, and tech enthusiasts understand the resolution of digital images in terms of megapixels.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{MP} \) — Megapixels (millions of pixels)
• \( \text{Width} \) — Horizontal pixel count
• \( \text{Height} \) — Vertical pixel count

Explanation: Multiplying width and height gives total pixels, dividing by 1 million converts to megapixels.

3. Importance of Megapixel Calculation

Details: Understanding megapixels helps determine image quality, print size capabilities, and storage requirements.

4. Using the Calculator

Tips: Enter the width and height in pixels (must be positive integers). Common resolutions:

• 1920×1080 (Full HD) = 2.07 MP
• 3840×2160 (4K UHD) = 8.29 MP
• 6000×4000 = 24 MP

5. Frequently Asked Questions (FAQ)

Q1: What exactly is a megapixel?
A: One megapixel equals one million pixels (1 MP = 1,000,000 pixels).

Q2: Does more megapixels mean better quality?
A: Not necessarily. While more MP allows larger prints, factors like sensor size and pixel quality matter more for image quality.

Q3: How many MP is a 4K image?
A: 4K resolution (3840×2160) is approximately 8.3 megapixels.

Q4: What's the MP of a 10×8 inch print at 300 DPI?
A: (10×300) × (8×300) = 3000×2400 = 7.2 MP needed for high-quality print.

Q5: How do I find an image's pixel dimensions?
A: Right-click the image file > Properties > Details tab (Windows) or Get Info (Mac).
