30°C is 303 Kelvin. Half of that is 151 Kelvin, which translates into a fairly mild -122°C!
Takes out hockey stick
New strategy to prevent global warming: just freeze all of the CO2 out of the air!
That’s one of the ways proposed for terraforming Venus. Put in a sun shield to freeze the planet, let the CO2 snow down, then process the CO2 into something that can sequester it away so it doesn’t just go back into the atmosphere after removing the sun shield.
Of course none of that is technically possible right now, but it’s a lot easier on a planet that has no (known) life to destroy while working through the process.
That sounds great. I bet it would be even easier to do on earth. If anyone gave a shit.
Aka a cool 272 Rankine for our US folks.
I would be willing to bet there are more people in the US using Kelvin in their jobs than Rankine.
Lb-mole? That one I’m not sure.
To me, these wanna-be scientific units are weird, like, just use metric at that point 😅
Also 1000th of an inch. Like, come on! You’re just teasing us
😱
Granted. Celsius now range from 0 to 50
Edit: … or whatever unit you prefer. It’s still the same
Oh, it’s way better than the alternative interpretation.
Half Kelvins?
30°C is 303.15K, half 151.575K is a nice and chilly -121.575°C lower than any recorded temp on earth by about 21°C. When working with monkeys paw or genies always declare your units and reference frames.
No.
wdym range from 0 to 50?
0 is the freezing point of water 50 is the boiling point.
If it’s 30°c outside, it will be only be 15 after the wish, thus fit what the character said
sure but you shouldn’t take halves on a scale with an arbitrary 0
True, but my joke wasn’t meant to be scientifically accurate at all. We have a genie here. They don’t care about science. Apart from monkey paw science

Obviously we’d all die but I wonder how exactly. This would make a good question for Randall Munroe.
90 F to Kelvin, halved and converted back, is approximately -190.
It’s difficult to find data on what exposure to that temperature would do, the threshold for an extreme cold warning (meaning absolutely do not go outside without heavy protection unless you want necrotic frostbite) is about 150 F warmer than that.
It depends on conductive and convective transfer at that point. The atmosphere would be vastly different as that’s well below the point where CO2 would snow out but you should still have enough gasses to flash freeze you.
I use this as an example for interval vs ratio; you can’t halve Celsius because it’s an interval scale where zero is arbitrary. Kelvin is ratio as it has an absolute zero-- you very much can halve it and doom near the entire planet next summer
Doom near the entire planet
Next Summer
Coming to theaters near you
arguably setting zero to absolute zero is just as arbitrary
Careful, half of what, kelvin?
That is indeed the joke.
Absolute-ly
A good genie would instantly invent a metric of “number of degrees in excess of room temperature”
Which room though?
what, you never heard of the room temperature room?
It’s a room made from platinum-iridium, and kept in a triple-locked vault at the International Bureau of Weights and Measures in France.
unfortunately, opening the door changes the temperature, so in practice instruments are calibrated from copies of the room built at other metrology institutions around the world.
Is that Kurt Angle?
I think it’s acute angle
No, it’s Kur Tangle
