32°F is 0°C which is why you need the 32 in there. For the fraction I always just try to think about whether Celsius or Fahrenheit is bigger. Accordingly, I’ll need a number smaller or larger than one.
edit:
Aight I got the fraction wrong, which kinda proves that it’s useless to remember lmao.
The easy way to remember the multiplier is that there’s exactly 180 degrees between boiling and freezing in Fahrenheit, and 100 in Celsius. Just use 1.8 instead of a fraction.
In Fahrenheit, 0 is the temperature of ice in some random brine, just as 0 in Celsius is the temp of ice water.
Fahrenheit and Celsius are defined nearly identically. Fahrenheit just chose some weird values for its basic constants, like using a weird ice brine instead of just ice water.
Man, come on. The ONLY time imperial makes some decent sense is temperature: for humans, 0 is really cold and 100 is really hot.
Edit: for anyone metric having a cow here, I am pro-metric. All I’m trying to say is that of all the hairbrained measurements in imperial, temperature is the least hairbrained.
What? Tropical regions regularly get that hot, are we supposed to believe that humans die off during the day and get replaced in the night?
I live in Maricopa county, and while yes people do die from the heat, it’s not really a substantial amount (about 400 out of over 4 million). It’s almost always the elderly or people with severe health problems.
The guy is way off with humidity levels. But look up wet-bulb temperature. Over 35C on the wet bulb scale which you egt with 40C and 70% humidity will kill you.
Do you know what temperature a hot tub is? That’s with nearly full body immersion, 40 C with 70 percent humidity is easily survivable.
Of course any outside temperature above 37 has a possibility of killing you, but those are the extreme outliers. If the claims being made here were accurate, humans wouldn’t exist, we would never have survived a tropical summer.
Again, no. As long as you can replenish water and electrolytes, you’re not going to die. It doesn’t take a few hours to kill someone by heat. If you are actually unable to regulate your body temperature, your core temperature will increase much faster than “taking a whole day”. It’s the loss of water and electrolytes that inihibits your metabolism and cooling that makes you die, not the heat taking several hours to permeate through your skin. (Human metabolism generates a lot of heat, so this idea is even more absurd if you think about it).
Read a physiology textbook, or even basic evolutionary biology if a human couldn’t survive 40C with humidity, humans would be extinct.
It seems like you talk about sweating - thats why you talk about the replenish water and ectrolytes part. I hope you know how sweating works and that it only works if the humidity is not too high.
So what do you think happens if the air temperature is over your body temperature and sweating dies not cool you down?
Maybe you should read a book. I am really curious about a biology text book that will tell me that 40C and 100% humidity is totally fine for humans for survive, lol.
your right. there is no true ‘objective’ scale for temperature. freezing/boiling water is arbitrary and not even that consistent. for 99% of use, farenheit is better for people. the biggest advantage that celsius has, is that it is the same scale as kelvin, but thats just because it was more popular in science. the rest of metric is good tho
How hot is that in the rest of the world?
306 kelvin
Its the same amount of hot in the rest of the world, just measured in different ways.
555.67 Rankine
Here’s how you convert between the two:
T[°C] = (T[°F] - 32)* 5/9
32°F is 0°C which is why you need the 32 in there. For the fraction I always just try to think about whether Celsius or Fahrenheit is bigger. Accordingly, I’ll need a number smaller or larger than one.

I find it easier to do mental arithmetic with the fraction (and I didn’t know the boiling point of water in Fahrenheit). But thanks anyways!
And the -32, hmm? Checkmate, atheists
32 degrees F is freezing, as is 0 C.
Ramen.

That edit lol I used to know this by heart at some point in my life. Now I’m fine knowing that it exists and use software to do it for me instead

Ah, yes. Subjectivity.
Pretty much no one uses F°
as opposed to the measurable freezing and boiling temperature of water?
At sealevel.
Since everyone lives near sea level, that can be safely omitted.
Yes all 8 billion people on earth live at exactly sealevel at all times.
They do, approximately. Did you miss the basic science class in which it’s made obvious that the crust of the Earth is thin as fuck?
You have never cooked a meal in Denver Colorado ;)
Is cooking that different in Denver?
More than a third of the entire world’s population lives within 100 meters of sea level. The average person lives at less than 500 meter of sea level.
100 is unacceptably hot. Nobody can live in that for long.
86f peak temperature with 35% humidity? Tolerable. Especially when the sun goes down and the temp drops but the humidity stays lower than like 55%.
But the next day of 95f peak temp followed by 76f nadir with 70% humidity overnight? People without A/C die. The homeless die.

You should have linked a physiology reference.

Of course you don’t die instantly. The guy above talked about temperatures like that over a longer period, i. E. A whole day.
People can survive 100C+ saunas for 15+ minutes. But 40C and 100% humidity will kill you after a couple hours.
Again, no. As long as you can replenish water and electrolytes, you’re not going to die. It doesn’t take a few hours to kill someone by heat.

Small world views. Places have hotter temps than that and more rural communities and do fine.
Not doubting your comment, but it is just localised to wherever you sourced that.
Temperature isn’t everything. Humidity (as awful as a measurement it is) matters significantly more.
At least humidity makes sense. 0% is dry, 100% is " the air is full"
your right. there is no true ‘objective’ scale for temperature. freezing/boiling water is arbitrary and not even that consistent. for 99% of use, farenheit is better for people. the biggest advantage that celsius has, is that it is the same scale as kelvin, but thats just because it was more popular in science. the rest of metric is good tho
