48 rem is equal to 768 pixels.
The conversion from rem to pixel depends on the root font size set in the browser or CSS. By default, 1 rem equals 16 pixels, so multiplying 48 rem by 16 pixels gives the total pixel value.

Conversion Formula
The formula to convert rem to pixel is:
pixels = rem × root font size (in pixels)
By default, the root font size in most browsers is 16 pixels. So, to find how many pixels correspond to a value in rem, multiply that rem value by 16.
For example, converting 48 rem to pixels:
- Start with the rem value: 48
- Multiply by root font size: 48 × 16 = 768
- Result is 768 pixels
This works because rem units are relative to the root element’s font size, which converts relative sizing into absolute pixel units.
Conversion Example
- Convert 12 rem to pixels:
- 12 rem × 16 pixels = 192 pixels
- So, 12 rem equals 192 pixels
- Convert 7.5 rem to pixels:
- 7.5 × 16 = 120 pixels
- Result is 120 pixels
- Convert 30 rem to pixels:
- 30 × 16 = 480 pixels
- Thus, 30 rem equals 480 pixels
- Convert 25 rem to pixels:
- 25 × 16 = 400 pixels
- Final value is 400 pixels

Conversion Definitions
rem: A CSS unit representing the font size relative to the root element of the document. Unlike em units, rem always uses the root font size, making it easier to maintain consistent sizing across a webpage, regardless of nesting or inheritance.
pixel: A pixel is the smallest addressable element on a digital display, representing a single point of color. In web design, pixels are absolute units used to define sizes and distances on screens, fixed and precise regardless of device scaling.
Conversion FAQs
Does changing the browser’s default font size affect rem to pixel conversion?
Yes, if the user changes the browser default font size from 16 pixels to something else, the rem conversion will reflect that new root size. So, 1 rem would equal whatever the root font size is at that moment, changing the pixel result.
Can rem units be different on various devices?
Rem units depend on the root font size, which can vary if CSS or browser settings changes. Devices themselves don’t change rem values, but user or developer settings altering the root font size will cause the pixel equivalent of rem to differ.
Why use rem instead of pixels in CSS?
Rem units provide scalable and accessible sizing, adapting easily to user preferences by linking to the root font size. Pixels are fixed, which can cause accessibility issues, while rem units allow text and elements to scale consistently.
What if the root font size is not 16 pixels?
If the root font size is different, for example 20 pixels, then 1 rem equals 20 pixels. Converting 48 rem would be 48 × 20 = 960 pixels. The formula always multiplies rem by the actual root font size, not a fixed 16.
Can you mix rem and pixel values for layout?
You can, but mixing units requires caution. Using rem for font sizes and pixels for fixed elements can cause inconsistencies in scaling and responsiveness. It’s better to maintain consistent units to avoid layout issues.
