The opening bit of this episode BROKE MY BRAIN. You start with Fahrenheit, and mention Celsius for international listeners, but then you continue on with Fahrenheit… in a conversation about the FREEZING POINT OF WATER and the MELTING POINT OF SNOW.
What the fuck are you doing, America? Seriously. How do brains work there that you think this is an acceptable way to talk about temperature?
Technically the freezing point of water and the melting point of ice are the same, but this was more a conversation about snow conditions. Snow melting has more to do with rain falling on it than the ambient temperature of the air, and the top layer turning into dangerous ice has different factors again.
But even in this example, saying “salty water freezes at zero fahrenheit” isn’t even technically correct, because zero was “established as the freezing temperature of a solution of brine made from equal parts of ice, water and salt”. And I’ve got a feeling nobody is adding water and ice and salt in equal parts to stop their driveway from freezing.
I can kinda understand why people say things like “fahrenheit is good for talking about the warmth of the air because it it based around human comfort”, even if I don’t think a scale for just one specific situation or thing is very helpful in this instance. But this wasn’t even a conversation about air temperatures in relation to human comfort. It was about snow conditions and ice. Nobody will convince me that Celsius isn’t the right scale to be working in there.
I can also understand it, but I still think it’s dumb. Nobody here has any trouble talking about the heat in celcius. Nobody in the UK that I met had literally any trouble talking about the temperature in Celsius. And I’ve met a bunch of Americans who claim they can tell one degree of difference in Fahrenheit, but I’ve never met one who could actually reliably prove it.
I will die on my hill that Celsius is perfectly good for science but Farenheit is the better scale for measuring human comfort. 0 is fucking cold and 100 is fucking hot. It’s not hard. You can even think of it on a clothing scale! 0 is wear all the clothes, 50 is jeans and light jacket, 100 is get as naked as legally allowed.
I have no strong preference for any temperature system I just wish there was only 1. If I were designing a new system that everyone would magically adopt it would basically just be C*2.56. Which pretty nicely fits everyone’s wants:
Absolute 0 = -700
freezing = 0
room temp = anything in the 50s
100 is basically the same as 100F and individual degrees are even smaller.
