I don't know. If you really want to know it, you need to ask the author

This is widely misunderstood.
The em unit isn't relative to pixels at all.
We are using the unit em because we *don't* want to set it in relation
to pixels, because we want the user to decide how many pixels one em is.
One element's size of 1em is relative to it's parent element's size.
If there is no parent element it is relative to the default font size
of the user's system.
Since MSIE/PC is working internally in points,
it's default font size is always 12pt.
12 points could be 12 pixels as well as 20 pixels.
