PX to CM

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 PX to Centimeters (cm) with Ease

Our PX to CM Converter streamlines the process of converting PX units to centimeters (cm) 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 PX to Centimeters (cm) Converter

  • Step 1: Set the Base Value Begin by entering the base value, which represents the reference font size in pt.
  • Step 2: Input the PX Value Next, input the specific px value that you want to convert into centimeters (cm) units.
  • Step 3: Convert to CM Finally, all you have to do is enter the px value to obtain the equivalent value in cm units.

How to Convert PX Units to Centimeters (cm)

Converting a px value to centimeters units is a straightforward process, thanks to the font-relative nature of px measurements. Here’s how you can do it:

cm = px * ( 2.54 / PPI )

From the given conversion, we can derive that:

1cm * 2.54 = 96px

96px = 1cm * 2.54 / 96

1px = 2.54 cm / 96

Or:

1px = 2.54 cm / PPI

Note: If you are working with web or css, the default PPI is 96px.

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 pt conversion.

Calculate the CM Equivalent: To convert a px value (e.g., 37.8px) to cm 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 1cm (1cm * 96px / 2.54 = 37.8px).

Apply the CM Value: Use the calculated cm value in your CSS declarations for properties such as font-size, margin, padding, or any other property that accepts length values. Replace the px measurement with the corresponding cm value to ensure scalability and responsiveness.

The formula to convert px to centimeters (cm) units is straightforward:

cm = px * ( 2.54 / PPI )

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 PX and CM Units

The distinction between px and centimeters (cm) 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, centimeters (cm) units behave differently. If you modify the font size of a parent element, any child elements using cm length units will adapt accordingly. This dynamic behavior makes centimeters unit invaluable for creating flexible and responsive designs, as they scale in relation to their context.
