How to Convert REM to PX

The key to converting a rem value to px is the font-size you declare on <html> element.

html{font-size: 16rem}

Then, you can use the formula and manually compute its px equivalent.

REM to PX Formula:

px = rem / base font

Difference Between REM and PX

To know the difference between rem and px, you need first to understand what they are what how they behave.

First off, they are measurements used on screen media or screens on various devices. They are units commonly used to measure lengths in CSS (Cascading Style Sheets).

The difference between them is that rem is a fix-size unit. If you say that this font is 16rem, it is absolutely 16rem wherever you put it. It's just that other devices may display it differently. A 16rem font on your computer monitor might be displayed differently on a 16rem font on your mobile phone. You get the idea. However, px unit is a scalable one. It adopts or shall we say, it is always be relative to the base font. So what is a base font now? It is the font size you declare on <html> tag.

<style >
font-size: 16rem;

So given you assinged a base font, when you set sizes on your<main>,<header>,<footer>,<article>,<div>,<nav>, Remember that px is relative to your base font assigned to HTML element. So if you say your base font-size is 16rem, that means that when you want an <aside> element to have 64rem width, you can assign 4px. So you can say:

width: 4px;

In addition, if you can notice, when you don't declare base font-size on your <html> element, fonts just becomes bold or bigger than the normal. When you declare this style on <html> element, the normal size will be respected by the browser.

Achieve Responsive Web Design With REM To Px Converter

In the world of web development, designers and developers often find themselves in the need to convert between different units of measurement, especially when it comes to font sizes. Two commonly used units in CSS (Cascading Style Sheets) are "rem" (root em) and "px" (pixels). To facilitate this conversion process, a Rem to Px Converter or Px to Rem Converter comes in handy. This tool allows users to convert font sizes from one unit to another seamlessly.

The Rem to Px Converter is an online tool designed specifically for developers and designers working on CSS-based projects. It simplifies the process of converting font sizes from "rem" to "px" and vice versa. By using this converter, users can easily and accurately determine the equivalent value in pixels for a given size in "rem" or vice versa.

This tool operates on a simple principle and convert REM to PX in CSS. The "rem" unit is relative to the root font size, while "px" is an absolute unit. The root font size is typically defined in the HTML or CSS file using the "html" or "body" selector. By default, the root font size is 16 pixels. The Rem to Px Convertertakes this default size into account when performing the conversion.

Let's say you have a font size defined in "rem" units and you want to convert it to pixels. You can simply enter the value in the Rem to Px Converter and it will provide you with the equivalent value in pixels. For example, if you want to convert 1 rem to px value, you enter "1 rem," the converter will display the result as "16 px" because 1 rem is equivalent to the default root font size of 16 pixels.

Similarly, if you have a font size defined in pixels and want to convert it to "rem" units, you can use the Px to Rem Code Converter. This converter takes the entered pixel value and divides it by the root font size to calculate the equivalent value in "rem" units. For instance, if you enter "24 px," the converter will display the result as "1.5 rem" because 24 pixels divided by the default root font size of 16 pixels equals 1.5 rem to pixels.

The Rem to Px Converter online is not limited to converting single values; it also supports batch conversions. This means you can enter multiple values separated by commas or spaces and the converter will provide the equivalent values for each of them. This feature of the pixel converter saves time and effort when working with multiple font sizes in a project.
