make 32 as the melting point of water, 100 as your own personal temperature, and voila.
Unfortunately the guy had a little fever when he did it, so the average body temperature is really 98F...
What's the sense of this scale? It's the least scientific thing I know... And why the hell some still use it??

0 is the temperature of some sort of ice-salt mixture.

It's not a great scale, but it was better than what they had before...

Farenheit was doing some pretty impressive pioneering work when he set his 0 and 100 values.

On the other hand, that "we" still use the Farenheit scale is just as stupid as using that Lbs Oz Feet Yards and Stone ...[text shortened]... ng to do with oligarchical elitist manipulations masquerading as political science? As if!

The elite will find a way, kind of like life in Jurassic Park. The question is - will they be warlords, businessmen, politicians or what?

Is it only the USA that still uses Imperial measurements?. I know Ireland completely switched over recently. And all of Europe is Metric. As is Australia. What about (aboot) Canada?, South America etc.....

Well, apparently, in the US some do and some don't:

The guy didn't have a fever. He tested the internal temperature of a pig, thinking that it would be the same as a human's. However, the pig's is slightly higher, so we were left with a regular internal temperature of 98.6 F. Or that's how the legend goes.

Every unit in the Imperial system, including temperature, was supposed to represent an aspect of human anatomy and biology. The foot was a way of measuring - you guessed it - a human foot. We were smaller back then, though . . . .

Everything has grown since then. The whole universe expands. Foot by foot.

It came before Celcius. It works for scientific work. It was good for it's time, but it's time has passed.

If I had my way, all thermometers would read in Kelvins.

Fahrenheit used his armpit and defined it as 96 according to Wiki. Why? IDK.

"Feet" were likely feet in shoes. We were smaller back then - so why aren't most peoples' feet longer than a foot? Average British male adult foot is ten inches.

"A hand cannot ever be longer than 11 inches. Well perhaps 11 and a half, maybe even 11 and three quarters, but not longer."
"Why?"
"Because if it is longer, then it would be a foot."

The scale defined by Celscius is not so clever either. It is defined as 0 degrees when water boils and 100 degrees when water freezes. Therefore it doesn't measure heat, rather it measures chill. Isn't this cool?
It was Linneus, the famous botanist, who turned the scale to what we have today. He was the clever one! He kept the name of Celcius so now we ...[text shortened]... Celcius thermometer.
Lord Kelvin used the the Celcius scale as a basis for his Kelvin unit.

Not to be picky🙂 but don't you mean 100 when water boils and 0 when water freezes?
Maybe there should be a standard based on absolute zero like Kelvin but when you look at that, where water freezes is somthing like 279 degrees.
So maybe you should have one that goes, absolute zero is 0 and where water boils is 1000 degrees. How bout that one?

Water would freeze at some strange temperature.

The scale that Celcius defined was actually not a measure of heat but more a measure of cold. At those times they didn't know much about wat heat actually was, nor what cold was. Antoine Lavoisier introduced an element he called Caloric, This element, was the carrier of heat. If you mix the two elemnts, water and Caloric, then you get hot water. If you extract Caloric from a piece of wood, you can actually see the Caloric, that's what fire is, and when the Caloric is out, then you cannot burn wood further, and it is cold.

Now we know that things warmer than others has more energy than others, and cold are absence of energy in some extent.

So Celcius defined Zero degrees where water has zero units of cold, where water boils. And Hundred degrees where water has maximum amount of cold, 100 degrees of cold. Water cannot have more than 100 degrees of cold because then it is not water anymore. Water cannot have less than 0 degrees of cold because then it vaporizes.

So no, I mean, according to Anders Celcius, just what I wrote, water boils in 0 degrees, and freezes at 100 degrees.

Later on, Carl von Linneus, the most brilliant botanist through times, turned the scale upside down, so we got the modern Celcius scale. He didn't change the name of the scale though, or else we would say, "Nice weather, 30 degrees Linneus!"

My calculations show water would freeze at almost exactly 732 degrees J.
(The J is the Jennings scale🙂 The difference between freezing and boiling would be 267.98 degrees J.
