Elara Bennett32 px equals 2 rem.
When converting pixels (px) to rem units, it depends on the root font size, which by default in browsers is 16 px. So, dividing 32 px by 16 gives 2 rem. This means 32 pixels is twice the size of the root font size.

Conversion Formula
The formula to convert pixels to rem is: rem = px / root font size. The root font size is most commonly 16 pixels in browsers, but it can be different if customized. This formula works because rem units are relative to the root element’s font size, making the design scalable and consistent.
For example, converting 32 px to rem:
- Start with 32 px
- Divide by 16 (default root font size): 32 ÷ 16
- Result is 2 rem
This means 32 pixels is equivalent to 2 rem units.
Conversion Example
- Convert 24 px to rem:
- Divide 24 by 16
- 24 ÷ 16 = 1.5 rem
- Convert 48 px to rem:
- Divide 48 by 16
- 48 ÷ 16 = 3 rem
- Convert 10 px to rem:
- Divide 10 by 16
- 10 ÷ 16 = 0.625 rem
- Convert 64 px to rem:
- Divide 64 by 16
- 64 ÷ 16 = 4 rem
- Convert 15 px to rem:
- Divide 15 by 16
- 15 ÷ 16 = 0.9375 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. In CSS, px defines absolute length, meaning the size stays consistent regardless of user settings or zoom, though device pixel density can affect appearance.
rem (Root em): rem is a relative length unit in CSS. It measures size relative to the root element’s font size, typically the <html> element. Using rem allows scalable, consistent sizing across a webpage, adapting when root font size changes without changing each element individually.
Conversion FAQs
What happens if the root font size is not 16 px when converting 32 px to rem?
If the root font size isn’t 16 px, the conversion formula changes accordingly. For example, if root font size is 20 px, then 32 px equals 32 ÷ 20 = 1.6 rem. So, the rem value depends on the root font size, not fixed at 16 px always. This affects how sizes scale on the page.
Why should I use rem instead of px in my CSS?
Using rem units makes your design scalable and accessible. Unlike px, rem sizes adjust if the root font size changes, which is helpful for user preferences or responsive layouts. Pixels are fixed, which can cause issues on different devices or for users with visual impairments.
Can browser zoom affect the px to rem conversion?
Browser zoom changes the visual size but not the actual CSS values. The px to rem conversion is based on root font size in CSS, so zooming doesn’t alter the conversion result. However, zooming can make elements appear larger or smaller visually, but their computed rem sizes stay the same.
Is rem supported in all browsers for converting px values?
Yes, rem units have wide browser support, including older versions of major browsers. They are safe to use for CSS sizing and converting from px to rem, providing consistency and flexibility across web projects.
How can changing root font size impact the layout when using rem?
Changing the root font size will proportionally scale all elements sized in rem units. For example, increasing root font size from 16 px to 18 px makes all rem-based sizes 12.5% larger. This is useful for responsive design or accessibility, but can cause layout shifts if not managed carefully.
