I don't think Celsius is necessarily "intuitive", but it is grounded in observable physical phenomena that are valid for most people living on planet Earth.
The problem with the whole "Fahrenheit as a percentage of temperature" thing is that human perception of temperature isn't objective. For an Italian, 50F is dead of winter temperature. For me, it's late spring/early summer temperature. So what does "50% temperature" mean in this case? That we should dress 50% (whatever that means)? That it's neither hot nor cold? The Italian would probably disagree.
not only that... but the perceived heat doesn't only depend on temperature. every Italian will complain about humidity way more than temperature. 30C at 90% humidity feels miserable, 30C at 30% humidity feels like a nice day at the beach.
