the temperature you can't measure but everyone in the room can feel

means Moderately cold in the pleasant sense, or — figuratively — calm, fashionable, and effortlessly admirable.

from From Old English 'cōl,' meaning literally chilly, a sibling of German 'kühl' and rooted in the same ancient source as 'cold.' For most of its life it just described temperature and unbothered tempers (a 'cool head'). The slang sense of stylish, excellent, and self-possessed is a 20th-century American flowering, often credited to Black jazz culture, where 'cool' named a whole laid-back aesthetic of restraint — and from there it spread into the everyday word of approval it is today.
