Fahrenheit makes sense for humans. Most of your day to day climates are in the 0 to 100 scale, and every 10 degrees is a noticeable level change.
100 super hot day, approaching unsafe without counter measures
90 really hot day, slightly annoying and should take precautions
80, hot day, more annoying than anything
70, beautiful day, enjoy it
60 not to bad, if it’s windy you could be slightly on the cold side
50 long sleeves or maybe a hoodie
40 definitely a jacket, and hat
30 full on coat, scarfe, and hat
20 multiple layers of out for a while, maybe double pants
10 annoyingly cold, need to start thinking about the safety precautions
0 and below, temperature now measured in hold long you can be outside before danger
Celsius makes sense for science stuff because it’s derived from science stuff, so things like calories and energy work with it. But it doesn’t really apply to everyday life as well. So it actually makes sense to use both units for the things the are good at.
Just an fyi, 100F is not “unsafe without counter measures” level of hot. That would be around 115+F. I say this as someone from a city that regularly hits 120F during the summer. 100 you can still get in your car, 115+ you need to wear gloves or else you’ll get 3rd degree burns. 100 have to buy pizza for lunch, 115+ just bake a pizza in your car.
Being from outside of the US I’m used to Celsius for everything, so I can make the same list, the numbers are just not whole 10s and I would probably round to nearest 5.
It depends on what you were raised with. For me I have all these relevant points in my head for C. 25 is nice, under 20 you slowly need to dress longer stuff. Over 30 is hot, over 40 sucks hard, over 50 can become deadly soon. Body temp is around 37.
I don’t science anymore, but living in a F country, I keep in mind for conversions:
0C is freezing point of water ~32F 20-22C is room temp ~68-72F 30C+ is Unhappy temperatures/hot.
Really only things I need to remember, and gradient based off of. It can get up to 45C where I live, but that would never be important to me. I hate the heat, if it’s 30C+, the degree to which it is hot matters little, I’m going to just want to stay out of the sun or go inside.
It’s just designed with a slightly different set of assumptions.
Instead of water freezing and boiling 100° apart, it’s 180° in fahrenheit. That makes it so that they’re on the opposite sides of a temperature gauge, and a degree of rotation of the gauge matches a degree of temperature.
Instead of zero being the freezing point of water under specific conditions, it’s a brine solution whose temperature will stabilize in a way that’s useful for using as a calibration point.
Stripped of its context, it’s odd. But it’s not irrational, just no longer consensus as the standard, and as such deprecated.
Never. They use the same spacing between degrees. The Kelvin scale was derived from the Celsius scale, just placing the 0° at absolute zero rather than at the freezing point of water.
My actual high school experience. I enjoy math these days. When I was expected to learn and demonstrate it, I was an unstable teenager unsure if I hated myself or my parents more. (Spoiler alert: it was my parents >_>) Doing math made me slow down and make space in my head, which let out all the dead Hanks and Deans allowed the TRUAMA to flood in.
