Pixels to Millimeters
PX is a crucial measurement unit frequently employed in Cascading Style Sheets (CSS). It serves as a font-relative unit, signifying that its value is in relation to the font-size of its parent element. This approach can significantly impact the consistency and scalability of your design.
Convert Pixels to Millimeters (mm) with Ease
Our Pixels to Millimeters Converter streamlines the process of converting Pixels to Millimeters (mm) values. You no longer need to manually calculate these conversions every time you require them. This tool simplifies the task, ensuring precision and efficiency in your CSS projects.
Note: In px unit, the base is the value of its parent's font-size. More information about this below.
How to Use the Pixels to Millimeters (mm) Converter
- Step 1: Set the Base Value Begin by entering the base value, which represents the reference font size in pixels (px).
- Step 2: Input the PX Value Next, input the specific px value that you want to convert into millimeters (mm) units.
- Step 3: Convert to MM Finally, all you have to do is enter the px value to obtain the equivalent value in mm units.

How to Convert Pixels to Millimeters (mm)
Converting a Pixels to Millimeters (mm) units is a straightforward process, thanks to the font-relative nature of px measurements. Here’s how you can do it:
px = mm * ( PPI / 25.4 )
1in = 2.54cm x 10 (*because there is 10mm in 1cm)
The result would be:
1in = 25.4mm
So base on the pixels conversion above, and the fact that 1 inch = 25.4 millimeters,
96px = 25.4mm
In other words,
1px = 25.4mm / 96
This yields to the result that 1mm is equal to 3.77952755906
Note: the 96px there is the Pixels Per Inch. In web, there are 96px in 1 inch. But in other screen and print media, you might need to set this to PPI value (ex: 300ppi)
Identify the Parent Font Size: Determine the font size of the parent element (often referred to as the container or wrapper). This font size will serve as the reference for your px conversion.
Calculate the MM Equivalent: To convert a px value (e.g., 37.8px) to mm units, simply divide the pixel value by the font size of the parent element. For example, if the parent font size is 37.8px, then 37.8px is equivalent to 10mm (37.8px * 25.4 / 96 = 10mm).
Apply the MM Value: Use the calculated Millimeter (mm) value in your CSS declarations for properties such as font-size, margin, padding, or any other property that accepts length values. Replace the pixel (px) measurement with the corresponding mm value to ensure scalability and responsiveness.
The formula to convert Pixels to Millimeters (mm) units is straightforward:
px = mm * ( PPI / 25.4 )
Understanding PX Units in CSS: When the parent element has a font size of 37.8px, 1cm equates to 37.8px for its child elements.
Understanding the Distinction Between Pixels and Millimeters Units
The distinction between px and millimeters (mm) units is straightforward yet crucial in web design. PX are absolute units, providing fixed measurements that do not change regardless of their context. In contrast, em units are font-relative, dynamically adjusting based on their parent element’s font size.
However, millimeters (mm) units behave differently. If you modify the font size of a parent element, any child elements using mm length units will adapt accordingly. This dynamic behavior makes millimeters unit invaluable for creating flexible and responsive designs, as they scale in relation to their context.
