Megapixel Formula:
From: | To: |
Megapixel calculation converts the total number of pixels in an image to megapixels (millions of pixels). It's a standard measure of resolution in digital cameras and displays.
The calculator uses the megapixel formula:
Where:
Explanation: One megapixel equals exactly one million pixels. This simple conversion helps standardize resolution measurements across devices.
Details: Megapixel count helps determine image quality, print size capabilities, and storage requirements. Higher megapixels generally mean more detail but also larger file sizes.
Tips: Enter the total number of pixels (width × height in pixels). The value must be a positive integer representing the pixel count of an image or display.
Q1: How do I find total pixels for an image?
A: Multiply the width by the height in pixels (e.g., 4000×3000 = 12,000,000 pixels).
Q2: Is higher megapixel always better?
A: Not necessarily. While more megapixels can capture more detail, they also create larger files and require better lenses to maintain quality.
Q3: What's a good megapixel count for printing?
A: For an 8×10 print at 300 dpi, you'd need about 7.2MP (2400×3000 pixels).
Q4: How does megapixel relate to sensor size?
A: Larger sensors can typically handle more megapixels without quality degradation compared to smaller sensors.
Q5: Does megapixel count affect low-light performance?
A: Generally, sensors with extremely high megapixel counts in small sizes may perform worse in low light due to smaller individual pixels.
