Or just converted +40C to +104F and assumed that the negatives must be the same.

Yeah, I thought this was reasonably well-known. Seems like I’ve known it since junior high or so. Maybe not super well known but like, not the $1,000,000 question on Who Wants To Be A Millionaire either.
Back in the 6th-8th grades we had a big thermometer on the wall with C on one side & F on the other. I distinctly recall noticing the -40C = -40F equality.
In math class, we “proved” this equality was, in fact, true and not just “close enough”.

Yeah, pretty simple to derive the conversion formula if you know 0C = 32F and 100C = 212F (or any other two points, but those are the most commonly known) and from there it’s easy to calc the break even. A good exercise for Algebra class.
“proved” by knowing the linear equation (F = (C × 9/5) + 32)? …or is it provable using this one weird trick that meteorologists don’t want you to know?

I can never remember the formula so I frequently derive it by recalling the freezing point and boiling point of water on both scales. That’s basically a proof of the conversion formula, and then it’s trivial to show that -40 is the break-even point.

Just don’t do that, Twig, when you are having any alcoholic beverages.
You should never drink and derive.
I remember learning this but not when or where. Math or science. BUT I don’t generally remember it when I’m doing conversions. And google is easier/faster.
I mean, I can do it in my head. 212 - 32 is 180. 180 / 100 = 1.8
1.8 C + 32 = F
Double check and 1.8 * 0 C + 32 = 32 F
1.8 * 100 C + 32 = 212 F
Yep, that must be right.

Wait? are you drinking?
I hope it wasn’t a digital thermometer, because that would mean a very cold day to be at school (although it would be memorable).
Well, it was MN, but, it was hung inside on a wall, and, no, we didn’t hold classes outside in the winter.

Coffee… does that count?
I’ve had school when the temp was -39.
In fact, we had about 2 weeks where the temperature never broke 0 F; then another 2 weeks where the temp was above 0 F for no more than 2 hours (in the afternoon).
The worst part of that stretch of cold was the two days where the high for the day was -25 F.

I have not lived anywhere that got that cold. But where I live now the kids get out of school if it’s too cold bc “they don’t have warm enough clothes”. Wind chill around 0 usually does it.
Whatever. The teachers deserve an extra day off since they’re still paid at 1995 rates.
The teachers in my school district mostly make six figure salaries.
For. Part. Time. Work.
It’s not really part-time during the school year. It’s just that teachers have 190 work days and the rest of us have somewhere in the vicinity of 225. That’s 84.4%, and most (though certainly not all) teachers are putting in more than 40 hours a week just for their regular teaching duties, not to mention extra for any extras they’re doing (extracurriculars, department head, internal subbing, Saturday school, etc.) and obviously if they teach summer school, or coach a sport that has summer workouts / camps or an extracurricular that goes over the summer then they’re working more than their contracted 190 days as well.
If you’re looking up their income on a public website it will include the pay for all of those extras, which can be considerable. Especially for intensive extra-curriculars like band or theater or cheerleading or coaching multiple sports (or even just one at a competitive varsity program). But it’s also a LOT of extra hours.
Is that actual wages or are you adjusting for your perception of the number of hours they’re working?
We had someone on AO who did that. He’d take like a $65,000 salary and argue that it was really over $100,000 based on some totally BS computation of how few hours he imagined they were working. But actually the teachers were taking home $65,000 or whatever.
So I’m just checking that you’re not making a similar error.
I won’t argue the case for your locale, but I have access to a fair amount of data regarding salaries of school employees and I am confident that most US teachers are not making 6 figures. Administrators maybe.
I know the teachers in my state are not making that.
