REM to PX
REM 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 REM to Pixels with Ease
Our rem in pixels Converter simplifies the process of converting REM units to pixel (px) values. 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 px unit, the base is the value of its parent's font-size. More information about this below.
How to Use the REM to PX 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 REM Value Next, input the specific rem value that you want to convert into pixel (px) unit.
- Step 3: Convert to PX Finally, all you have to do is enter the rem value to obtain the equivalent value in PX units.

How to Convert rem in pixels Units
Converting a 1rem to pixels units is a straightforward process, thanks to the font-relative nature of rem 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 PX Equivalent: To convert a REM value (e.g., 1rem) to px units, simply multiply the rem value by the font size of the parent element. For example, if the parent font size is 1rem, then 1rem is equivalent to 16px (1rem * 16px = 16px).
Apply the PX Value: Use the calculated px value in your CSS declarations for properties such as font-size, margin, padding, or any other property that accepts length values. Replace the rem measurement with the corresponding px value to ensure scalability and responsiveness.
The formula to convert rem to pixels (px) units is straightforward:
px = rem * font-size
Understanding rem Units in CSS: When the parent element has a font size of 1rem, 1rem equates to 16px for its child elements
Understanding the Distinction Between REM and PX Units
The distinction between rem and pixels (px) 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, px units behave differently. If you modify the font size of a parent element, any child elements using px 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
