Samantha Nicole24 px equals 1.5 rem.
To convert pixels (px) to rem, you divide the pixel value by the root font size, which is often 16px by default in most browsers. So 24 px divided by 16 equals 1.5 rem. This means 24 pixels is 1.5 times the base font size.

Conversion Formula
The formula to convert pixels (px) to rem units is:
rem = px / root font size.
The root font size normally is 16px on browsers, which means 1 rem equals 16 pixels. To convert, you divide the pixel value by this root size. For example, 24 px converts to rem by calculating 24 ÷ 16, which equals 1.5 rem.
This works because rem units are relative to the root font size, allowing scalable designs that adjust with user settings or CSS changes.
Conversion Example
- Example: 32 px to rem
- Identify root font size: 16px
- Divide 32 by 16: 32 ÷ 16 = 2
- Result: 32px equals 2 rem
- Example: 8 px to rem
- Root font size is 16px
- Calculate 8 ÷ 16 = 0.5
- So, 8px is 0.5 rem
- Example: 40 px to rem
- Root font size = 16px
- 40 ÷ 16 = 2.5
- Therefore, 40px equals 2.5 rem
- Example: 12 px to rem
- Root font size of 16px
- 12 ÷ 16 = 0.75
- Result: 12px is 0.75 rem

Conversion Definitions
px: A pixel (px) is a unit of measurement in digital imaging representing a single point on a screen. Pixels are absolute units and define the smallest controllable element of a picture on a display device. The size of a pixel changes with screen resolution and device.
rem: The rem unit stands for “root em” and is a relative length in CSS that scales based on the root element’s font size. Unlike px, rem scales according to user settings or browser defaults, enabling flexible, scalable layouts that adapt to accessibility needs and responsive designs.
Conversion FAQs
What happens if the root font size is not 16px when converting 24 px to rem?
If the root font size differs from 16px, you must divide 24 by the actual root font size to get correct rem value. For example, if root font size is 20px, then 24 px equals 24 ÷ 20 = 1.2 rem. Always check the root font size before converting to rem.
Does using rem instead of px improve website accessibility?
Yes, using rem units helps scale text and elements based on user preferences or browser settings, improving readability. Pixels are fixed sizes, which may not adjust well on different devices or for users with visual impairments, but rem provides a flexible, scalable approach.
Can negative pixel values convert to rem?
Negative pixel values can be converted to rem by dividing by the root font size just like positive values. While rarely used, negative rem values might be used in CSS for positioning or animations where offsets go in opposite direction.
Why does converting 24 px to rem sometimes produce different results in some designs?
Different results occur when the root font size changes in CSS or browser settings. If a website sets the root font size to a value other than 16px, the conversion factor changes, so 24 px might not always equal 1.5 rem in those cases.
How to quickly convert 24 px to rem without calculator?
Knowing the default root font size is 16px helps. Divide 24 by 16, which equals 1.5. You can memorize common conversions or use simple mental math by breaking down the pixel number into multiples of 16 for rapid conversions.
