2 rem equals 32 pixels (px) assuming the root font size is 16px.
This conversion depends on the default browser font size, commonly 16px, so multiplying rem value by 16 gives the equivalent pixels. Here, 2 rem × 16 px = 32 px.

Conversion Formula
The formula to convert rem to px is:
px = rem × root font size in pixels
Since the root font size in most browsers is 16px by default, multiply the rem value by 16.
Why? Because rem units refer to the font size of the root element (<html>), so 1 rem equals the root font size.
Step-by-step for 2 rem:
- Identify root font size: 16px
- Multiply rem value by root size: 2 × 16 = 32
- Resulting pixel value is 32px
Conversion Example
- Convert 3.5 rem to px:
- Root font size is 16px
- 3.5 × 16 = 56
- So, 3.5 rem equals 56 px
- Convert 0.75 rem to px:
- 16px × 0.75 = 12
- 0.75 rem is 12 px
- Convert 5 rem to px:
- 5 × 16 = 80
- 5 rem equals 80 px
- Convert 1.25 rem:
- 1.25 × 16 = 20
- 1.25 rem equals 20 px

Conversion Definitions
rem: A CSS unit that means “root em”, which measures size relative to the root element’s font size. Unlike em, rem always references the root font size, making it consistent across nested elements. It allows scalable, accessible designs that adapt to user preferences.
px: Pixels represent absolute screen units, measuring one dot on display. They don’t scale with font size or user settings and provide precise control over layout dimensions. Pixels are fixed units that help designers specify exact sizes, independent from the parent or root element.
Conversion FAQs
Can the root font size affect the conversion of 2 rem to px?
Yes, the root font size directly influences rem conversions. If the root font size changes from 16px to 20px, 2 rem becomes 40px instead of 32px. The rem unit always multiplies by whatever the root font size currently is, which can vary with CSS or browser settings.
Why might 2 rem not equal exactly 32 pixels in some browsers?
Some browsers or user settings alter the default root font size, so 1 rem isn’t always 16px. Accessibility settings, zoom levels, or custom CSS can modify the root size, making 2 rem convert to a pixel value different from 32px.
Is rem better than px for responsive web design?
Rem adapts to user preferences and root font size changes, making it flexible for responsive layouts. Pixels are fixed and don’t scale, which can cause usability issues on different devices. Using rem can improve accessibility and consistency across screen sizes.
Can negative rem values be used and converted to px?
Technically, CSS allows negative values for some properties using rem units, and they convert by multiplying the negative rem by the root font size, resulting in negative pixels. However, many CSS properties do not accept negative sizes, so usage is limited.
How does zooming a page affect rem to px conversion for 2 rem?
Zooming in a browser changes the effective root font size visually, so 2 rem may appear larger or smaller in pixels on screen. However, the CSS pixel values remain the same; only the rendered size changes because the browser scales the layout.
