At least it wasn’t measured in campfires or number of hotcakes.
Damn now I kinda wanna know how many campfires this is equivalent to
A full burning campfire can hit 2000 F, so this would be about 90,000 of those
I don't think temperature works like that though lol
180 million Fahrenheit converts to almost exactly 100 million Kelvin, so I imagine the journalist just converted from Kelvin to get that number. Anyway, using 2000 F ≈ 1,366.48 K gives about 73,000 bonfires.
Temperature does kinda work like this. The Boltzmann constant k_B has units of Joules per Kelvin (energy / temperature). An energy E can has an equivalent temperature T given by setting E = k_B*T. I think it’s good enough to state that 73,000 bonfires would be collectively 73,000 times hotter than one bonfire.
And how many bonfires is a campfire?
About 2 campfires for a bonfire I guess. A normal campfire isn’t going to be 2,000 F, more like 800 F but let’s call it 1,000 F. I thought bonfire was more accurate above because the fire would have to be roaring to reach that temp.
that's honestly less campfires than I'd expect
The ones hot enough for marshmallows?
It's a fuckton.
