600 px equals 37.5 rem.
To convert pixels (px) to rem, you divide the pixel value by the root font size, which is commonly 16 px in browsers. So, 600 px divided by 16 equals 37.5 rem, meaning the element will scale relative to the root font size.

Conversion Formula
The formula to convert pixels to rem units is: rem = px ÷ root font size. The root font size is the base size in pixels that browsers use for 1 rem, often set to 16 px by default. This means every rem corresponds to 16 pixels unless changed by CSS.
How this works is by making measurements scalable: rem units depend on the root font size, so changing that size scales all rem-based values proportionally. This is useful for responsive design.
Example calculation for 600 px:
- Start with 600 px.
- Divide 600 by 16 (default root font size).
- 600 ÷ 16 = 37.5 rem.
- So, 600 px equals 37.5 rem.
Conversion Example
- Convert 320 px to rem:
- 320 ÷ 16 = 20 rem.
- Thus, 320 px equals 20 rem.
- Convert 480 px to rem:
- 480 ÷ 16 = 30 rem.
- So, 480 px equals 30 rem.
- Convert 750 px to rem:
- 750 ÷ 16 = 46.875 rem.
- Therefore, 750 px equals 46.875 rem.
- Convert 1000 px to rem:
- 1000 ÷ 16 = 62.5 rem.
- So, 1000 px equals 62.5 rem.
- Convert 128 px to rem:
- 128 ÷ 16 = 8 rem.
- Therefore, 128 px equals 8 rem.

Conversion Definitions
px (pixel): A pixel is a single point in a digital image or display, representing the smallest unit of measurement on screens. Pixels measure screen resolution and size, influencing how content appears visually. The pixel size can vary by device, but it remains a fixed unit in CSS.
rem (root em): Rem is a scalable unit in CSS relative to the root element’s font size. Unlike px, rem adjusts according to the root font size, allowing flexible and consistent sizing across different screen sizes or user settings. Rem units improve accessibility and responsive design.
Conversion FAQs
Why does converting 600 px to rem depend on root font size?
The conversion depends on the root font size because rem units are relative to it. If the root font size changes, the resulting rem value for 600 px changes too. For example, if root font size is 16 px, 600 px becomes 37.5 rem, but if root is 20 px, 600 px equals 30 rem.
Can I use rem instead of px for fixed layout designs?
Using rem allows layouts to scale with user preferences or device settings, but for fixed pixel-perfect designs, px might be better. However, rem offers flexibility and accessibility by adapting sizes, which is generally preferred for responsive designs over rigid px units.
What happens if the root font size is not set to 16 px?
If the root font size changes from 16 px to another value, the conversion formula must adjust accordingly. For instance, with a root font size of 14 px, 600 px converts to 600 ÷ 14 = 42.857 rem instead of 37.5 rem. This affects the scaling of elements sized in rem.
Does converting px to rem affect image sizes on websites?
Images sized in px remain fixed unless CSS specifies otherwise, but if image dimensions use rem, their size scales with root font size. Converting px to rem for images can make them responsive to font scaling, but caution is needed to maintain visual quality and aspect ratio.
How accurate is the conversion from px to rem?
The conversion is mathematically exact based on the root font size, but browser rendering and rounding can cause minor visual differences. Using rem helps maintain proportional scaling, but pixel-perfect accuracy might vary slightly depending on device and zoom settings.
