We don't target the html/css stack yet. But we want to. So i think it is important to count it in as soon as possible. CSS rendering of "real world units" seems stable but does not work exactly the way you would expect. CSS user agents assumes a 96 ppi screen [1]. On my 113 ppi screen a 10 cm div renders as a 8.5 cm div. Exactly the behavior I don't want: 1 cm in code, 85 mm on screen. This may of course still be helpful as a fixed northern star. Given the 96 ppi and the browsers rendering we could calculate the run time screens ppi: 96 / (8.5 / 10) ). 1. http://www.w3.org/TR/CSS21/syndata.html#length-units
