Convert Pixels to Millimeters (MM)



Formula

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

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

Example

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.
