16 pixels equals 1 rem.
The value of 16 pixels is converted to rem by dividing it by the root font size, which is commonly 16 pixels. This means 16px divided by 16px equals 1rem, making it a direct and simple conversion.

Conversion Formula
To convert pixels (px) to rem, divide the pixel value by the root font size (commonly 16px). The formula is:
rem = pixels ÷ root font size
This works because rem units are relative to the root element’s font size in CSS, making layouts scalable. If the root font size changes, rem values adjust automatically.
Example calculation:
- Given 16 pixels
- Root font size = 16 pixels
- rem = 16 ÷ 16 = 1 rem
Conversion Example
- Convert 24 pixels to rem:
- Divide 24 by 16
- 24 ÷ 16 = 1.5 rem
- Convert 32 pixels to rem:
- Divide 32 by 16
- 32 ÷ 16 = 2 rem
- Convert 8 pixels to rem:
- Divide 8 by 16
- 8 ÷ 16 = 0.5 rem
- Convert 12 pixels to rem:
- Divide 12 by 16
- 12 ÷ 16 = 0.75 rem
- Convert 20 pixels to rem:
- Divide 20 by 16
- 20 ÷ 16 = 1.25 rem

Conversion Definitions
Pixels: Pixels are the smallest unit of measurement on digital screens, representing one point in a raster image or display. They define the resolution and size of elements in web design, graphics, and images, differing in actual physical size depending on screen density.
Rem: Rem stands for “root em” and is a CSS unit relative to the font size of the root element (usually <html>). It allows scalable, consistent sizing across a webpage, adapting automatically if the root font size changes, unlike fixed pixel units.
Conversion FAQs
Why does converting 16 pixels to rem result in 1rem?
Because the default root font size in browsers is 16 pixels, dividing 16px by this root size equals 1rem. This makes 1rem the equivalent of 16 pixels unless the root font size is changed by CSS.
What if the root font size is different than 16px?
If the root font size changes, the conversion ratio changes too. For example, if the root font size is 20px, then 16 pixels equals 0.8rem (16 ÷ 20). This means rem units depend on the root size, so 16px won’t always equal 1rem.
Can I mix pixels and rem units in the same stylesheet?
You can mix them, but it may cause inconsistent scaling. Pixels are fixed size units, whereas rem scales with the root font size. Using rem is preferred for responsive designs, but mixing requires careful handling to maintain harmony.
Why use rem instead of pixels for font sizes?
Rem units scale relative to the root font size, allowing better accessibility and responsive layouts. If users adjust their browser font size, rem-based text scales accordingly, unlike fixed pixel sizes which remain static.
Are negative pixel values valid for rem conversion?
Negative pixel values can be converted mathematically to negative rem values, but in practice, negative sizes for fonts or dimensions aren’t meaningful or valid in rendering. They might be useful in calculations but rarely used for styling.
