How to Use Instant PX to Mm Converter

This simple calculator instantly converts pixels (PX) to Millimeters (mm). 

By default, the calculator assumes a default DPI of 96, which is quite common in web development. However, you have the option to customize this default setting to match your preferred screen DPI.

Pixels and Millimeters

•••

The pixel, abbreviated as ‘px’, is the basic unit of programmable color on a digital display.

Each pixel is a sample of an original image, whereas more samples typically provide a more accurate representation of the original.

On the flip side, we have Millimeters.

A millimeter, the smallest standard metric measurement, is a unit of length equal to one thousandth of a meter. Millimeters, part of our everyday life, are extensively used in the real-world measurement of small objects.

Converting Px to Mm

Converting from pixels to millimeters involves a key component DPI (Dots Per Inch) or PPI (Pixels Per Inch), the measure of pixel density or the resolution of a screen.

Under standard screen conditions (96 DPI, a common desktop screen resolution), the formula to convert pixels to millimeters is as follows:

Millimeters = pixels / (DPI / 25.4)

Here ‘25.4’ is the number of millimeters in an inch. So, if we have a 200px image displayed on a standard screen, using the formula, we get:

Millimeters = 200px / (96 / 25.4) ≈ 52.92mm

This conversion implies an on-screen display. For print contexts, you might use a DPI of 300 or 600, as these are standard print resolutions.

The actual physical size that a pixel measurement represents can change drastically between different devices due to the variance in DPI.
