Pixel to Mm Calculator

Formula

The formula to convert Pixels to Millimeters (MM) is:

\[ \text{MM} = \frac{\text{P}}{\left( \frac{\text{DPI}}{25.4} \right)} \]

Where:

Pixel to Mm: A conversion metric used in digital imaging to translate the digital pixel units into physical millimeters. This conversion is crucial in graphic design, printing, and other fields where the physical size of an image or object is important. The conversion rate is not fixed and depends on the resolution or DPI (dots per inch) of the digital image. Higher DPI values result in more pixels per millimeter, leading to a higher level of detail in the printed image.

Let's say the size in pixels (P) is 300 and the resolution (DPI) is 72. Using the formula:

\[ \text{MM} = \frac{300}{\left( \frac{72}{25.4} \right)} \approx 105.83 \, \text{mm} \]

So, 300 pixels at 72 DPI is approximately 105.83 mm.
