About PX to REM Converter

A PX to REM (and vice versa) converter is a useful tool that simplifies the process of switching between two crucial units in web design—pixels (PX) and root ems (REM).

Here’s the gist:

REM: This unit is relative to the base font-size set on the root HTML element. For example, if the default font size is 16px, then 1 REM will equal 16px. The beauty of REM is its scalability; if you change the root font size to 18px, everything sized in REM adjusts proportionally.
PX: Pixel is an absolute unit, meaning it stays constant regardless of the screen size or any other settings.

Converting Between PX and REM:

To get PX from REM: Multiply the REM value by the root font size.
- Formula: [Root Font Size] x [Size in REM] = [Size in PX]
To get REM from PX: Divide the pixel size by the root font size.
- Formula: [Size in PX] / [Root Font Size] = [Size in REM]

By using a PX to REM converter, you can easily switch between these units without manual calculations, making your web design process quicker, more precise, and more accessible.

If you’re a web developer or designer, you’re probably no stranger to the world of unit conversions in CSS. From pixel to rem converter tools to px to rem conversion formulas, it’s a topic that comes up often, especially when aiming for responsive and accessible design.

In this guide, we will delve into how to convert px to rem, the benefits of using rem over px, and how to use online tools like a px to rem calculator to simplify your workflow.

The Basics: What is REM?

Before we dive into the pixel to rem converter options, it’s essential to understand what REM (Root EM) is. It’s a flexible unit of measurement in CSS that stands for “root em” and is relative to the root element’s font size, typically set on the element.

How PX to REM Converter

So, you’re staring at a style guide and wondering how to convert 18px to rem, or perhaps 20px to rem. The good news is, converting px to rem is a simple task:

Determine the Root Font-Size: This is the foundational step for rem conversion. The default root font-size in most browsers is 16px.
Use the Formula: To convert any px value to rem, divide the px value by the root font-size. For example, 18px in rem would be

PX to REM Converter Tools

Using a px to rem calculator or a pixel to rem converter online can help automate this process. Just plug in values like 12px to rem or 100px to rem, and these tools do the heavy lifting for you.

When to Use REM over PX

Understanding when to use rem vs px is crucial for responsive design. REM units are relative, scalable, and make your life easier when dealing with a variety of devices and user settings. For instance, if you need to set a size between 15px and 25px, using rem will make it easier to manage those styles across different screen sizes.

Converting REM to PX

The road doesn’t end at converting pixels to rem; you might also need to convert rem to px. For this, multiply the rem value by the root font-size. For example, 1.125rem to px would be $1.125 \times 16 = 18 p x$ , and 1.5rem to px would be $1.5 \times 16 = 24 p x$ .

Advanced Conversions

There are also edge cases to consider. What if you need to convert something like 1.875rem to px or .5rem to px? The formula still applies: just multiply by the root font-size to get your answer.

Units Comparison: REM vs. EM vs. VH/VW

The landscape of CSS units is vast, including not just rem and px, but also em, vh, and vw. So, how do these compare?

REM vs EM: REM is always relative to the root, whereas EM depends on its closest parent. For example, 1rem in px is a constant, but 1em in px can vary.
REM vs VH/VW: These units are relative to the viewport dimensions. For instance, vh vs px can be seen as comparing apples and oranges: they serve different needs.

Beyond Pixels and REMs: Percentages and Font Sizes

You can also convert px to % for certain CSS properties. Just like converting 14px to rem, you can convert it to a percentage based on the parent element. The same goes for font sizes; a font-size rem to px conversion can be easily done with our formula or a specialized font-size converter online.
