Honestly, I get your point, but I don’t think it’s necessarily a property of the scale, rather your increased familiarity with it. When someone says 68F I don’t have a mechanism to understand that, it’s not part of my experience. Saying 68% of too hot doesn’t help much at all. Whereas I can tell you exactly what I 40C feels like; and how that compares to anything from -15C to 45C, because of my familiarity with the scale.
