the vertical iPhone viewport width is 320 px, but what is the width in ems
or
what is the default font size in px in the iphone
A:
320px = 20ems. I think the default size is 12px; it's set to "Medium", which in most cases is 12px.

An em is based off the point size of the font. 320px will be 20ems only if the font is a 16 point font.

Does this help? http://www.evotech.net/blog/2007/07/web-development-for-the-iphone/
But maybe you can use a variation of this: http://www.everythingicafe.com/forum/iphone-software/increase-font-size-in-safari-without-zooming-9511.html
to set a font size that stays the same, which would answer your question.

A:
I did a test with the viewport set to the iphone width:
<meta name="viewport" content="width=device-width" />
and...
<span style="font-size:16px">A</span>
is the same size as
<span style="font-size:1em">A</span>
both in the vertical and horizontal orientation
