Megapixels To DPI Converter
This is a free and easy-to-use converter that you can use to convert megapixels to dpi (dots per inch) accurately.
Megapixel is one million (1,000,000) pixels that form an image. megapixels are one of the important characteristics of a monitor and a digital camera. Also in megapixels, the size of the created or scanned image is measured to correlate its size with the size of a known image.
The aspect ratio of an image is the proportional ratio of width to height. You know it as two numbers separated by a colon in x:y format.

Manually and online megapixels to dpi conversion
You can convert megapixels (MP) to dpi either manually or online.
To convert MP to dpi manually you need the following formulas:
First formula to calculate width in pixels:
Width in pixel = √(Aspect ratio * megapixel value * 1000000)
Second formula to calculate height in pixels:
Height in pixel = √(1/Aspect ratio * megapixel value * 1000000)
Third formula to calculate diagonal in pixels:
Diagonal In Pixels = √(width² + height²)
Finally, calculate the dpi value:
DPI = Diagonal In Pixels/Diagonal In Inches
To convert megapixels to dpi online, you can use the above converter for fast and accurate conversion.
