EM vs PX: How are they different?
Em and Px are both units of measurement that are commonly used in web design. Pixel, also known as “px”, is a fixed unit of measurement that is based on the resolution of the device being used to view the content. On the other hand, EM is a relative unit of measurement that is based on the font size of the parent element. This means that if the font size of the parent element is changed, the size of the EM unit will also change.
One of the main benefits of using EM over pixels is that it can provide a more flexible and responsive design. Since the EM unit is based on the font size of the parent element, it can adapt to changes in font size, making it a good choice for responsive design. On the other hand, pixels are fixed, and do not respond to changes in font size, making them less flexible.
Understanding EM and REM units
EM and REM are similar, but they are not the same. Both units are relative, meaning that they are based on the font size of the parent element. However, there is one key difference between the two. EM is based on the font size of the immediate parent element, whereas REM is based on the font size of the root element (usually the <html> tag).
The main advantage of using REM over EM is that it allows for more consistent sizing across different elements. Since REM is based on the root element, it does not change based on the font size of the parent element, making it more consistent. However, this can also be a disadvantage in some cases, as it can make it more difficult to make precise adjustments to the font size of individual elements.
Why is the em to px calculation based on base pixel size?
The conversion from pixels EM to PX is based on a base pixel size, which is typically the font size of the root element. This is because the EM unit is a relative unit that is based on the font size of the parent element. By using the root element as the base, it provides a consistent starting point for all font sizes.
To calculate the EM value of a pixel size, you need to divide the pixel value by the base pixel size. For example, if the base font size is 16px, and you want to convert a pixel value of 24px to EMs, you would divide 24 by 16, giving you a value of 1.5 EMs.
How to use a tool to convert em to px?
A EM to PX converter tool is a useful tool for web designers who want to quickly and easily convert pixel values to EMs. To use a EM to PX conversion tool, follow these simple steps:
- Visit to our online tool website Tools360.net and search “EM to PX converter” OR Directly search on google “EM to PX Tools360”.
- Once you visit, then simply enter the pixel value that you want to convert into the Em value.
- Ans there you go, will get the converted PX value automatically
- NOTE: You also can change the base font size in pixels. This is typically the font size of the root element, which is often set to 16px by default.
