Em a javascript tool used to convert size in pixel to relative EM units that are based on text size which helps in accessing CSS design.

When ever you try to convert the  Pixel to EM just give a pixel value to ems  so, by default body’s font size for scope is used but a scope property which is in the form of a jQuery selector can be passed to handle conversions those are relative to that particular elements font size.

The default font size is 16px where 1em is equal to 16px, and 12px is equal to 0.75em so to convert the pixel to em a method was developed by clagnut this method simply sets the body element’s font size to 62.5% where the value of 1em becomes 10px this allows n easy calculations just by dividing a pixel value by 10.

How to size text in CSS using em is so simple:

Let us assume that a browser we are using is set to a medium text and the default size for this medium text is 16px and here our first step is to reduce this size for the entire document by setting the body size to 62.5%

Body {font-size: 62.5%}

This will take the 16px text to 10px text that would be easy to set the size in terms of ems, for example, 1em is 10px and 0.8em is 8px.

Em is used with pixel that allows elements and text to scale identically. Most of the browsers like internet explorer cannot scale text that is set in text so ems are used and so all of the pages can proportion to that text size
