1. What is a Megapixel?

A megapixel (MP) is equal to one million pixels and is a term used to describe the resolution of digital cameras and displays. It's calculated by dividing the total number of pixels by 1,000,000.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Total\_pixels} \) — The total number of pixels (width × height)
• \( 1000000 \) — Conversion factor from pixels to megapixels

Explanation: This calculation converts the raw pixel count into the more commonly used megapixel measurement.

3. Importance of Megapixel Calculation

Details: Understanding megapixels helps in comparing camera resolutions, determining image quality potential, and calculating print sizes.

4. Using the Calculator

Tips: Enter the total number of pixels (width × height) from your image or camera specifications. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Does more megapixels mean better quality?
A: Not necessarily. While more megapixels can mean higher resolution, image quality also depends on sensor size, pixel size, and processing.

Q2: How many megapixels is 4K resolution?
A: Standard 4K (3840×2160) is about 8.3 megapixels (3840 × 2160 = 8,294,400 pixels).

Q3: What's a good megapixel count for printing?
A: For an 8×10 print at 300 dpi, you'd need about 7.2 megapixels (2400×3000 pixels).

Q4: How do I find total pixels from width and height?
A: Multiply the width in pixels by the height in pixels (e.g., 4000×3000 = 12,000,000 pixels).

Q5: What's the megapixel of Full HD?
A: Full HD (1920×1080) is about 2.1 megapixels (2,073,600 pixels).
