Yep Celsius is 1-100 for water and Fahrenheit is 1-100 for humans

This is why Celsius is the only SI unit that isn’t just wholly better than its imperial counterpart. Both F and C are fairly arbitrary, but in my view F has the slight edge by giving numbers 0-100 in most weather conditions across earth.

I’ve always hated this justification of Fahrenheit. For it to be a good argument, 50 °F would need to be the ideal comfortable temperature. But instead 50 is really fucking cold. 100 just isn’t as hot as 0 is cold.

I think it depends on the person which is the problem, for me 50 isn’t that cold but 100 is completely unbearable

Fully agree with you. How does that make sense:
Really hot summer days (30°C) are 86°F
Usual summer days (25°C) are 77°F
Room temperature is ~70°F
Spring / autumn days (20°C) are 68°F
Chilly outside / late autumn / early spring days (~10°C) are 50°F
Cool outside / warm winter days (~0°C) are 32°F
Cold outside / usual winter days (~ -10°C) are ~15°F
Winter nights (bit below -20°C) are ~ -10°F

I mean, I deliberately avoided using terms like “hot summer days” and “usual winter day” because that’s far more dependent on where you are. Where I am it’s:
- Really hot summer days (35 ℃)
- Usual summer days (30 ℃)
- Room temperature (24 ℃)
- Spring / autumn days (25 ℃)
- Chilly outside (18 ℃)
- Cold outside / usual winter days (15 ℃)
- Winter nights (10 ℃)
So I used words that are about the experience of a person in those temperatures in comfortable light clothing, rather than times of year. And obviously there’s some subjectivity there, with some people being more comfortable in cold temperatures than others. But still, we’re talking about the comfortable mid point varying from mid 20s to high 10s. There’s no reasonable world in which 50 ℉ (10 ℃) is the midpoint.

Only if you grow up with it lol. Fahrenheit makes no sense to me

how is fahrenheit 1-100 for humans? 100 i can sorta see, most people have a body temp around ~37°C (though still, there’s about 1°C of variance…), but 0°F is very very cold and not exactly a temperature that many people encounter on a daily basis.
i certainly cannot think of anything more relevant to humans than the freezing and boiling points of water, most people encounter them often and it’s very easy to see when water starts freezing or boiling.
If you see ice outside you know the temp is below °C, when the water in your pot is boiling you know it’s at 100°C, it’s super fucking easy.But the reference points for fahrenheit cannot intuitively be measured, 0°F has no obvious indicator, and 100°F can at best be vaguely inferred based on the air temps we can do work in, and even then you can really only reliably infer something like 30°C because that’s generally when humans start feeling like it’s too warm to do significant amounts of labour.

Kelvin is the SI unit. Anyway also for the weather Celsius is clearer: Below 0 = snow, above 0 = rain. And Celsius at least has fixed points that can be recreated - if all thermometers and data on scales were lost we could easily recreate °C, but not °F.

Ah well I should have said metric measurement then. It is part of the metric system, yes?
If you can’t remember the number 32 then I guess. Personally I think it’s pretty bizarre to have negative temperatures all the time but whatever floats your boat.
Regarding losing all thermometers and data… if you lost the definition of Celsius there would be no way to recreate it. This seems nonsensical.

No seriously what is significant about 0F? I live in a place that sees a lot of negative F too.
It’s so arbitrary. If it was 0 at freezing water and 100 at human body temp I’d understand it but no, it’s literally nothing significant in people’s lives. It has no tangible anchor.
It’s purely emotion keeping it around.

0°F is the coldest night Mister Fahrenheit has ever seen, thinking it couldn’t become any colder than this.
100°F is Mister Fahrenheit’s slightly feverish body temperature.
???
PS: Pretty much all other countries also had their own measurement systems and simply switched to metric because it made sense. I’m glad we did, and pretty much all others did too.
PPS: I’d also be up for revamping time measurement, why can’t we have 10h a day, 100 minutes per hour, 100 seconds per minute? 100.000 seconds in total per day, currently we have 86.400 so a second would only become slightly shorter.

Nothing. It’s equally arbitrary as setting 0 to be the freezing point of water.
But it covers the weather for the vast majority of people, the vast majority of time, better than Celsius does. That’s what I mean.
If you want to remove sentimentality from your temperature then use Kelvin but Celsius is just as arbitrary and sentimental as Fahrenheit is.
