Me "knowing" the system doesn't help me. Because I have no idea what 325°F really is. That would cook my skin, no way I'm "feeling" it. All it is is just a number to me. If I had to push 325 or 163 on my oven it makes no difference to me.

When someone says I put a liter of gas in my car, I can reasonably think and know what a liter is. To me, the easiest way is that it's half of a 2L of soda because soda is sold in metric liters, and it gives me a reference. I also know that a liter is basically 1/4 gallon.

But when you say 28°C, I have nothing to compare it to. I know 40°C is really hot, and 20°C is basically room temperature. Even that doesn't even help me. So I guess I can deduce it's somewhere in the middle? It's 82°F. But I have no reference to how 28°C feels.

82°F. Is low 80's, I know what low 80's feels like. Easy for me to figure out the realitive temperature.

Fahrenheit and weather temperatures just line up so good at 0-100.

But if you just thought of 82°F as 82% hot you could easily get a general idea of how hot it is.

Livable temperatures are between 50°F and 100°F. Humans like it halfway between the two. ~75% hot. 65°F is a cold house, 85°F is a hot house. 99% of homes are between those two and still averages to 75°F.

1°F is smaller than 1°C.

82°F vs 83°F a normal person wouldn't be able to tell the difference. But you know, as it approaches 85°F or 90°F it's definitely heating up.

I could say 93°F. 93% hot. That's pretty hot. I'm sure you could wrap your mind around that.

But tell me 34°C and how am I suppose to really quickly wrap my head around that?

6° less than the hottest realistic temperature outside? I don't even know how 1°C drop feels, much less 6°.
