The limits of "hot" and "cold" change with location and personal experience. 0°F is shorts weather for some, while 70°F is jacket time for others. Both live in my neighborhood.

There are hundreds of millions of people who see negative double digits every year, and billions of people who have never seen snow (Mumbai has never seen below 50°F!). There is no scale that can claim to cover human's experience of temperature in general, but some scales can be useful.

The exact numbers don't matter to people anyway, no one sees 70°F and estimates 70% hot, just like most of the world knows what 22°C means, even if it never freezes there. We could measure in yoctojoules (40.7) or simply relative to what the pope feels is hot and cold (85?). For daily use all temperature scales are arbitrary. Why not use one that's useful?

Only for those with medical issues or those being obstinate. It's not a relevant data point when trying to agree on a scale. 99.9% of people will agree 0F = cold as fuck.

So? The difference between 0F and -10F and -25F aren't THAT significant. The VAST majority of people will treat those temperatures as similar unless they're preparing for an outdoor adventure or something. But the difference between 65 and 75 is HUGE to most people that WILL impact how they prepare for interacting with the environment.

This is just not accurate and is pure cope. A scale that's 0-100 for the most important temperatures that humans interact with is an objectively good scale. With 10 degree bands that align pretty well to general human comfort and indicate the type of preparation required. Sure, some people might consider 60s t-shirt weather, but the point is the band is still relevant. 60-70, 70-80, 80-90. Those are useful, meaningful temperature ranges where the temperature inside those bands is similar enough
