48 rem equals 768 pixels.
This conversion is based on the default browser font size, which is commonly set to 16 pixels. Multiplying 48 rem by 16 pixels per rem gives the pixel value, making it easier to understand dimensions in web design.

Conversion Formula
The formula to convert rem to pixel is:
pixels = rem × root font size
Browsers use a default root font size of 16 pixels unless changed by CSS. Rem stands for “root em,” meaning measurements relative to that root font size.
For 48 rem:
- Multiply 48 (rem) by 16 (pixels per rem)
- 48 × 16 = 768 pixels
This formula works because rem units scale with the root font size, so converting to pixels requires multiplying by the root font size in pixels.
Conversion Example
- Convert 12 rem to pixels:
- Step 1: Take 12 rem
- Step 2: Multiply by 16 (default root font size)
- Step 3: 12 × 16 = 192 pixels
- Convert 25.5 rem to pixels:
- Step 1: Take 25.5 rem
- Step 2: Multiply by 16
- Step 3: 25.5 × 16 = 408 pixels
- Convert 7 rem to pixels:
- Step 1: Take 7 rem
- Step 2: Multiply by 16
- Step 3: 7 × 16 = 112 pixels
- Convert 33 rem to pixels:
- Step 1: Take 33 rem
- Step 2: Multiply by 16
- Step 3: 33 × 16 = 528 pixels
- Convert 50 rem to pixels:
- Step 1: Take 50 rem
- Step 2: Multiply by 16
- Step 3: 50 × 16 = 800 pixels

Conversion Definitions
rem: The rem unit is a CSS length measuring relative to the root element’s font size. Unlike em units, rem references the root html font size, so it stays consistent regardless of nesting. This helps maintain scalable and predictable layouts across a webpage.
pixel: A pixel is the smallest unit of a digital image or display, representing a single point of color. In web design, pixels are absolute units used for fixed-size measurements. One pixel corresponds to one dot on the screen, though physical size varies with device resolution.
Conversion FAQs
What happens if the root font size is changed from 16px?
If the root font size changes, the conversion from rem to pixel also changes because rem is relative to that root size. For example, if the root font size is 20px, then 48 rem equals 48 × 20 = 960 pixels instead of 768. So, rem units adapt to the root font size set by CSS.
Can rem units be used for responsive designs?
Yes, rem units help with responsive designs because they scale based on the root font size. Changing the root font size dynamically (for example, with media queries) adjusts all rem-based sizes proportionally, making layouts more flexible across different screen sizes.
Why choose rem over pixels in CSS sizing?
Rem units offer scalability and accessibility, unlike pixels which are fixed. Using rem allows text and elements to resize consistently when users adjust base font size settings, improving readability and user experience, especially for those with visual impairments.
Is 16px always the default root font size?
Most browsers set 16px as the default, but it can be changed by user settings or CSS on the page. Because of this, rem values might not map to 16 pixels in every situation, so designers test on different devices to ensure consistent appearance.
How accurate is converting rem to pixel in different browsers?
Conversion accuracy depends on the actual root font size used by the browser or CSS. While 16px is standard, user preferences or stylesheets can alter it, affecting pixel equivalents. Testing on target browsers ensures the expected pixel values match the rem measurements.
