PX to MM Converter
Use this free online px to mm converter tool to convert pixel values to millimeters. Millimeters are an absolute unit used for precise print measurements, where 1mm equals approximately 3.78 pixels. This converter is valuable for print stylesheets requiring metric precision.
To convert pixels to millimeters, multiply the pixel value by 25.4 and divide by 96 (since 1 inch = 96px and 1 inch = 25.4mm). This follows the CSS specification for absolute unit relationships. The result provides precise millimeter measurements.
Conversion Formula
mm = (px × 25.4) ÷ 96
For example, to convert 96px to millimeters, calculate (96 × 25.4) ÷ 96 = 25.4mm. Similarly, 3.78px approximately equals 1mm because (3.78 × 25.4) ÷ 96 ≈ 1.

What is PX?
Pixels (px) are an absolute CSS unit representing a single dot on screen, normatively defined as 1/96th of an inch. They are commonly used for precise element sizing in web design. However, pixels can create accessibility issues as they don't scale with user browser preferences, making them less ideal for responsive typography.
What is MM?
Millimeters (mm) are an absolute CSS unit representing physical millimeters, primarily used for precise print measurements. In web contexts, 1mm equals approximately 3.78 pixels. Millimeters are most useful in print stylesheets and international design contexts where metric precision is required.
