One particular functionality I have in mind is to display an object in the browser window with predictably accurate stated physical dimensions. IOW, one inch always measures one inch; one cm always measures one cm; 12pt always measures 12/72", etc.
Note that is not how they are defined in CSS officially. Actually, 1cm = 96px/2.54according to official web standards,
Whether what any CSS "web standard" says, official or otherwise, depends on context. The issue here is virtually the same usurpation that occurred with well established decimal multiples being hijacked by the binary computing world, trying to redefine units with previously uncontroverted meanings. (kilo, mega, giga, etc.) At least those eventually got a reasonable fix.[1]
A centimeter isn't a centimeter unless it measures an ISO standard centimeter. When I open a web page that says something measures a centimeter, if my ruler doesn't measure it a centimeter, it isn't a centimeter, regardless what is contained in CSS standards.
That's what I would expect, yes. One centimetre measured with a plastic rule right on the screen. Not an apparent size. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
