Conversion Formula
The conversion formula to change rem to px is:
pixels = rem × root font size (in px)
Usually, the root font size is 16 pixels, so the formula becomes pixels = rem × 16.
This works because rem is a unit relative to the root element’s font, which is often 16px by default in browsers. When you multiply the rem value by 16, you get the equivalent absolute pixel value.
Example calculation for 3.4375 rem:
- Start with 3.4375 rem.
- Multiply by 16 (root font size): 3.4375 × 16 = 55.
- So, 3.4375 rem equals 55 pixels.
Conversion Example
- Convert 2.25 rem to px:
- Multiply 2.25 by 16: 2.25 × 16 = 36.
- Result: 2.25 rem equals 36 px.
- Convert 0.5 rem to px:
- Multiply 0.5 by 16: 0.5 × 16 = 8.
- Result: 0.5 rem equals 8 px.
- Convert 4.125 rem to px:
- Multiply 4.125 by 16: 4.125 × 16 = 66.
- Result: 4.125 rem equals 66 px.
- Convert 1 rem to px:
- Multiply 1 by 16: 1 × 16 = 16.
- Result: 1 rem equals 16 px.

Conversion Definitions
rem: The rem unit in CSS means “root em,” which measures sizes relative to the root element’s font size. Unlike em, rem always refers to the root, so it provides consistency across different elements and simplifies scaling. It helps in making web pages scalable and accessible.
px: The px unit stands for pixels, a fixed-size unit in digital displays. Pixels represent the smallest unit of measurement on a screen, and they are absolute, meaning their size does not change based on other elements. Pixels are used to define exact sizes in layouts and graphics.
Conversion FAQs
Can the conversion from rem to px change on different browsers?
The conversion depends on the root font size, which defaults to 16px in most browsers. However, users may change browser settings or stylesheets might alter the root font size. In those cases, 1 rem can represent a different number of pixels, changing the conversion result.
What happens if the root font size is set to something other than 16px?
If the root font size changes, the rem unit scales accordingly. For example, if the root font size is 20px, then 3.4375 rem equals 3.4375 × 20 = 68.75 px. The conversion formula must always use the current root font size to get accurate results.
Is rem better than px for responsive design?
Rem units can be better for responsive design because they scale based on the root font size, making it easier to adjust layout sizes dynamically. Pixels are fixed, so using rem allows more flexible resizing and accessibility, but pixels give precise control when needed.
Does negative rem value have any practical use?
Negative rem values are possible but rarely practical. They might be used for offsetting elements in CSS. When converted to px, negative rems produce negative pixel values, which can move elements in the opposite direction, but should be used carefully to avoid layout issues.
Why does the conversion tool sometimes show blank results?
The tool requires a valid numeric input. If the input is empty, zero, or not a number, the output will be blank to avoid confusion. Make sure to enter valid numeric values to see the conversion result in pixels.
