Is it possible to think of a measure, which is proportional to the 
angular size of a feature at hand? according to: "as viewed at normal 
conditions for a particular display"?

I mean: a measure that will represent the same amount od "steradians" 
irrespectively of the fact, that the "thing" (like a font) is displayed 
on 5" FullHD (1900x1080) galaxy note, and an old 14" notebook screen of 
800x600 pixels, or for that matter: 60" UltraHD TV, taking into account, 
that those displays are normally used at different distances from eyes, 
like: 24cm, 70cm, 2m respectively.

I'm looooning for something like pica-point-steradian (ps), defined so, 
that "font-size: 10ps" would render as 10pt font  on kindle (and would 
print as 10pt font on paper), and when rendered on my notebook would 
"apear" to me as 10pt font on paper held "at bended arms length" .... so 
would render on such screen to 12pt or similar.

No more dpi, px, pt, cm, in,... those should be hidden by 
display/browser internals.
