What is Pxtoem.net?
pxtoem.net is a handy online conversion tool for web developers and designers. It allows you to quickly and easily convert pixel (px) values to em units that can be used in CSS code.
Using em units instead of pixels for properties like font-size, margins, padding, etc. is considered a best practice in web development since it allows elements to scale better responsively across different screen sizes. Em is a relative unit that is relative to the font-size of the parent element.
The pxtoem.net tool is very simple and easy to use. You just enter the pixel value you want to convert, choose the base font-size that you are using in your CSS, and it will instantly calculate and display the equivalent em value.
For example, if you enter 16px with a base font size of 16px, it will convert and display 1em. If you enter 12px with a base of 16px, it will display 0.75em. It handles decimal values as well in the conversion.
The tool works seamlessly and also shows the calculation it is doing, which is 16px / 16px = 1em. Very useful for quick em value conversions without having to calculate manually.
