PX to REM
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 REM with Ease
Our pixels to rem Converter simplifies the process of converting pixel (px) values to REM units. You no longer need to manually calculate these conversions every time you require them. This tool streamlines the task, ensuring precision and efficiency in your CSS projects.
Note: In rem unit, the base is the value of its parent's font-size. More information about this below.
How to Use the PX to REM 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 pixel (px) value that you want to convert into REM units.
- Step 3: Convert to REM Finally, all you have to do is enter the px value to obtain the equivalent value in REM units.

How to Convert Pixels (px) to REM Units
Converting a pixel (px) value to rem units is a straightforward process, thanks to the font-relative nature of px measurements. Here’s how you can do it:
html {font-size: 1rem}
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 em conversion.
Calculate the REM Equivalent: To convert a pixel value (e.g., 16px) to rem units, simply divide the pixel value by the font size of the parent element. For example, if the parent font size is 16px, then 16px is equivalent to 1em (16px / 16px = 1rem).
Apply the REM Value: Use the calculated rem value in your CSS declarations for properties such as font-size, margin, padding, or any other property that accepts length values. Replace the pixel measurement with the corresponding rem value to ensure scalability and responsiveness.
The formula to convert pixels (px) to rem units is straightforward:
px = rem / font-size
Understanding REM Units in CSS: When the parent element has a font size of 16px, 1rem equates to 16px for its child elements.
Understanding the Distinction Between PX and REM Units
The distinction between pixels (px) and rem units is straightforward yet crucial in web design. Pixels are absolute units, providing fixed measurements that do not change regardless of their context. In contrast, rem units are font-relative, dynamically adjusting based on their parent element’s font size.
However, rem units behave differently. If you modify the font size of a parent element, any child elements using rem length units will adapt accordingly. This dynamic behavior makes px units invaluable for creating flexible and responsive designs, as they scale in relation to their context.
