Comprehensive explanation of pixel px to em conversion.

Description
With CSS, "em" is a relative unit that is mostly used for font-size, meaning that its value is determined by the parent element's font size. The parent element's font size determines the sizes of all other child elements that use the em unit if it is specified. 1em is always equal to the current font-size of its parent, 0.5em would be half, and so on. The use of em units facilitates font size scaling and adjustment without compromising individual elements, thereby preserving a consistent user experience.
To convert pixel px to em, divide the px value of child element by the font-size of the parent element. For instance, if the parent element's font size is 16px and the child element's font size needs to be set to 10px then the corresponding em value of the child element is equal to (10/16) = 0.625 em. Our tool makes it simple to convert pixels px to em quickly.
