If it’s 50 degrees Fahrenheit then it’s 20 degrees Celsius. Double that and it’s 100F, and only 37C.
10C doubled to 20C is 50F and 68F.
On nice spring days I’ve always said “wow, it’s almost twice as hot today as it was last week.” But I don’t think that’s even remotely accurate.
Is Kelvin the only way to accurately measure something like this? If so, 300K is 80.33F and if you were to double it, you get 600K and 620.33F.
Would we ever be able to say “It’s twice as hot today as X time in the past?”
In: 0
Kelvin would be the way to go since it’s an absolute scale. 0 Kelvin is as cold as it gets.
So, by converting to kelvin and then doubling that and converting that to whatever other temperature scale you want will tell you the answer you want.
So obviously it can’t be twice as hot as it was at some other time because that would not be good. Double 0C is 273C, for instance. The coldest temp. recorded on Earth was -89C. Double that is 95C. That wouldn’t be a survivable temperature.
