Megapixel Calculator is a free online tool that allows you to quickly convert pixel dimensions into megapixels. By entering the width and height in pixels, you can instantly find out the total resolution in MP, making it ideal for photographers, designers, and anyone working with digital images.
What is eDPI?
EDPI stands for “Effective Dots Per Inch,” which is a measurement of mouse sensitivity in FPS (First Person Shooter) games. EDPI combines the DPI (Dots Per Inch) setting of a mouse and the in-game sensitivity setting to give a single value that represents the mouse’s overall sensitivity.
How to calculate eDPI?
An EDPI calculator can be used to find out the EDPI of a mouse by inputting the mouse’s DPI and the in-game sensitivity.
The formula for EDPI is simple: EDPI = DPI * sensitivity.
For example, if a mouse has a DPI of 800 and an in-game sensitivity of 2, the EDPI would be 1600.
It is important to note that different games may have different sensitivity settings, so a mouse’s EDPI can vary depending on the game being played. Additionally, different players may have different preferences for mouse sensitivity, so it is a matter of personal preference when choosing an EDPI value.
📸 What is Megapixel?
One megapixel (MP) equals 1,000,000 pixels. It represents the resolution of an image based on the total number of pixels from its height × width.
🧮 How to Calculate Megapixels?
To calculate the megapixel value of an image, use the formula:
Megapixel = (Width × Height) / 1,000,000
Example: If an image has a resolution of 4000 × 3000 pixels, the total number of pixels is 12,000,000 → 12 MP.
🔍 Why Megapixels Matter?
- Higher megapixel = more image detail and clarity
- Lower megapixel = smaller file size and faster loading
- Important for printing, editing, and digital photography

🆚 Megapixels vs Resolution
Megapixels refer to the count of pixels (in millions), while Resolution defines the dimensions of the image. For example, 4000 × 3000 resolution equals 12 MP.

FAQ
❓ 1. What is a Megapixel Calculator?
A megapixel calculator helps you convert pixel dimensions (width × height) into megapixels, allowing you to determine the total resolution of an image or camera sensor.
❓ 2. How do you calculate megapixels from pixels?
To calculate megapixels:
Megapixels = (Width in pixels × Height in pixels) ÷ 1,000,000
For example, 4000 × 3000 pixels = 12 MP.
❓ 3. Why is a Megapixel Calculator important for photographers?
Photographers use megapixel calculators to estimate print sizes, crop limits, and image clarity. It ensures the image resolution meets the desired quality standards before printing or publishing.
❓ 4. What is the difference between Megapixel and DPI?
Megapixels measure image resolution, while DPI (dots per inch) measures print density. They work together to determine how sharp an image appears when printed.
