Tl;dr: just round. This goes both ways.
Converting a 1 significant digit number must not increase the number of significant digits.

would someone explain to me why whenever european people are confronted with the idea of the imperial system their brain seems to shutdown into a slow state of oxygen preservation?
“40c in f is 104???” yeah, round it, its 100f, you think we specify to the Nth degree here?
“86f doesn’t really make sense” yeah, round it. 90 is pretty close, and who boy 90s are pretty hot.
“why isn’t 50f the perfect temperature” you’re literally just applying an arbitrary point on something entirely arbitrary. But ok. (also it is the perfect temperature range between 50-70f)
“how is -17c and 37c cold and hot???” literally round it bro, -20 and 40c are right there wow look at that now it makes more sense! Im pretty sure this commenter is aussie or something, so in their defense, anything under 70f is cold for them. Either that or they don’t wear clothes, ever, because they’re calculating the coldness with no clothing. for some reason.
“yeah but we also think of things in relation to the temperature of water, like freezing is when shit is icy, and also the relation to the boiling point” brother, water boils in fahrenheit as well (212f, but again, you’re going to shocked by this one, you can round it down to 200f, wow look at that, it’s like, pretty close.) sure the freezing point is still higher, but you really only get freezes here at super prolonged periods of just under 30f weather, or really cold snaps that stick around a bit. generally snow in 30f weather is, not really a thing, the ground is still warm enough it melts. ice doesn’t form unless it’s like, close to 0.
guys, i promise, it’s not this hard. Just, think about it a little bit, please. You’re killing me here!

Idk why you guys are so passionate about this whole rounding thing? Rounding off 107 to 100 doesn’t change the information, only the precision. It’s not easier to interpret 200 than 212 or anything?
If you want quick conversion, just
F ≈ 2 * C + 30

I like how this directly goes against the argument of Fahrenheit being more “graded” with integers lol
Gladaed@feddit.org 3 months ago
If you fail to provide uncertainty it suggest that Celsius is much more complicated because you need to pay attention to decimal points.
If you write 200 it would be anything between ±50and ±1 if you say 212 it means ± 2/1

literally this, just round.
This is what i do every time i have to think about celsius, i have rough equivalency ranges which often get my estimations into celsius within 1 or 2 degrees of the actual answer. All i need to know is a few rough datapoints and i can get a really usable output.
It’s actually just a skill issue.
uienia@lemmy.world 3 months ago
The thing is that you need to learn celsius if you are doing science, but celsius users don’t really need to learn fahrenheit, so this isn’t really a problem that comes up for a lot of celsius users.
KillingTimeItself@lemmy.dbzer0.com 3 months ago
yeah, and it’s like not that hard. If you talk to people that use fahrenheit on the regular, you should learn how to convert to fahrenheit right off the dome, just as they should learn to convert between celsius to fahrenheit as well.
Literally anything else is unreasonable lol.
hakase@lemm.ee 3 months ago
This is horrible logic. If anything, it should be: you need to learn Celsius if you are doing science, but most people aren’t scientists and therefore don’t need to learn Celsius, so this isn’t really a problem that comes up for a lot of Fahrenheit users.

There’s a reason why drug dealers and those who have huffed too much under the fume hood still know metric like the back of their hand.
KillingTimeItself@lemmy.dbzer0.com 3 months ago
idk if they know it like the back of their hand. But to be fair, anybody with the collective ability of about half a brain cell can use the metric system, so that’s not really saying much.

I assure you, you get icy roads and snow at 28-30f. Upstate NY gets tons of snow and most of that is above 25f. I don’t see it get in the teens too much. Single digits or colder is pretty rare. All depends on the region up here. Due to the lakes, it is all over the place.
KillingTimeItself@lemmy.dbzer0.com 3 months ago
it depends on where you are, obviously, but out here we generally don’t get snow into about the 20-25f range, and we rarely get snow that sticks around 30f, it does snow then, but it all melts. as i previously said.

smooth_tea@lemmy.world 3 months ago
You’re missing the point. The issue with Fahrenheit is not about the conversion from Celsius, most Europeans don’t need to do that anyway. The problem is Fahrenheit in itself, it’s just not elegant or scientific and therefore comes off as arbitrary and only makes sense when you grow up with it.
KillingTimeItself@lemmy.dbzer0.com 3 months ago
yeah but why does that matter? It’s all relative, the only good thing about celsius is that it happens to line up nicely with one specific elements boiling point. If you’re doing science the only redeeming quality is that it maps linearly to kelvin, which is nice.
some of the relative math is nice, for certain units. But outside of that, for like, temperature, and cooking where none of that matters?
