Trying to learn Fahrenheit scale isn't that easy as an adult. I know 0 is very cold and 100 very warm. So of course it follows 50 is perfect weather. Turns out it's not.
In the end you still just have to learn by hearth that t-shirt weather starts at 70 something and that kind of stuff.
50°F is the point where you need clothes to survive. If you sat naked in a 50°F room you run the risk of your body not being able to generate enough heat and you'll slowly die.
~75°F is room temperature. It's in the middle on the warm side.
70°F is a cool room, 80°F is a warm room.
Whenever I think of Celsius I see it as 0° to 40° with 20° being room temperature. I hear 30°C and think halfway between 70 and 100 so I know it's around 85°F and I know how 85°F feels.
But like 35°C. That's 3/4 of the way from 20°C to 40°F. 100°F-70°F is 30°. 3/4 of 30 is 22.5. So 35° must be close to 70°+22.5° or ~93°F. I know how 93°F feels.
I can see how celcius is easier if you learned it as a child. 35°C would just be 35°C. But trying to quickly wrap your head around it is difficult unless you just know it. I'm sure if I said 93°F you could tell me that that is pretty hot.
75F would already be a warm room for many. 70F or 21C is usually room temperature around here. In the past this was often 65F. In more southern places 75F is middle of the night temperature and too cold.
I can see how the F scale makes some sense, but then you see some news report from Texas reaching 100F and you wonder if people can read their own temperature scale as that is clearly not fit for human habitation.
