Px to Millimeters Converter

Millimeters (mm) are a unit of length used in the metric system. They are used to measure physical size, particularly in the printing and graphics industries. In digital imaging, pixels and millimeters are used together to describe the physical size of an image or object displayed on a screen. The conversion between pixels and millimeters depends on the pixels per inch (PPI) value of the display screen or printer being used, with higher PPI values resulting in smaller physical sizes for a given number of pixels. Pixels to millimeters (px to mm) converter is a tool used to convert pixels to millimeters, based on a specific pixels per inch (ppi) value.

How to Convert Px to Millimeters?

To convert pixels (px) to millimeters (mm), use the following formula:

mm = (px * 25.4) / PPI

Where:

  • mm = length in millimeters
  • px = number of pixels
  • PPI = pixels per inch of the display screen or printer
  • 25.4 = number of millimeters per inch

For example, if you have an image with 500 pixels and the display screen has a PPI value of 96, the size of the image in millimeters would be:

mm = (500 * 25.4) / 96 = 127 mm

It's important to note that the conversion factor may differ depending on the specific device used, so it's important to use the correct PPI value for the device you are working with.
