This tool helps you calculate the total number of megapixels for a given width and height in pixels.
How to Use the Megapixel Calculator
To use this megapixel calculator, simply follow these steps:
- Enter the width of the image in pixels in the “Width” field.
- Enter the height of the image in pixels in the “Height” field.
- Click the “Calculate” button to see the result.
How It Calculates
The calculator determines the megapixels of an image by multiplying the width and height of the image in pixels. It then divides the result by 1,000,000 to convert the pixel count into megapixels (MP). The formula used is:
Megapixels = (Width x Height) / 1,000,000
Limitations
This calculator assumes that you input the width and height in pixels and does not account for other units of measurement. It also requires that you input positive numerical values for both width and height. If either value is invalid, the calculator will display “Invalid input”.
