Yeah, 100°C is pretty warm

[–] hemko@lemmy.dbzer0.com 76 points 1 month ago (3 children)

0°C = outside the sauna

100°C = inside the sauna

[–] markz@suppo.fi 37 points 1 month ago (6 children)

100 degrees is uncomfortably hot for a sauna. Somewhere around 80 is good.

100 warm

Yeah, I suppose that's one way to describe 100°C

C is even more intuitive than the graphic.

0 = water's frozen 100 = water's boiling

[–] panda_abyss@lemmy.ca 48 points 1 month ago (2 children)

I had an American explain “well you just know that 68 is long sleeve warm, 80 is shorts” or something, as if people cannot memorize that 18 is chilly and 21/22 is usual room temperature, 26 is shorts.

The only thing I dislike like about Celsius is that my thermostat supports both, but doesn’t allow half degrees Celsius, so it provides less granular control in Celsius than if you set it to Fahrenheit.

[–] Magister@lemmy.world 35 points 1 month ago (4 children)

I'm in Québec, -10 is chilly, 14 is shorts :)

[–] frank@sopuli.xyz 15 points 1 month ago

I was about to say, in Denmark i definitely have shorts on in the teens, else I'd barely need to own any

As you approach 0°F it is getting dangerously cold. As you approach 100°F it's getting dangerously hot. Celsius is obviously better scientifically, but fahrenheit is pretty reasonable for everyday use (unlike other imperial measurements).

[–] panda_abyss@lemmy.ca 14 points 1 month ago (2 children)

Really my point is you can memorize new numbers when you look at the weather report.

When I go (went ) to the US it was not obvious to me looking at the weather in Fahrenheit what it would feel like.

[–] otter@lemmy.zip 13 points 1 month ago

Of course. I'm just adding that there is some logic to fahrenheit in day to day use.

Most metric units are designed around water in some way. Very easy to convert to different units because of this. 1mL of water is equal to 1g of water which is equal to 1 cubic cm of water, for example.

And weight also revolves around water. 1L of water is 1KG which is 1000cm^3^ whereas 1cm^3^ is 1g. Super easy to calculate things.

Edit: correction

Calling the boiling point of water simply "warm" is a bit sus.

My water does not describe 100°C as "warm"

People who say 100°C is warm make my blood boil.

As a European living in the US now for many years the temperature scale is the least of my annoyances. It's easy enough to memorize be ranges for what to wear. Fahrenheit is more granular, which is nice sometimes but really doesn't matter.

No, let's convert all the ridiculous weight/volume measures first. Having two kinds of ounces makes no sense. Measuring solids by volume (mostly) doesn't make sense. Having different units for different magnitudes doesn't make sense.

Fortunately things are often labeled in both metric and customary units so I can convert way easier.

Now if you'll excuse me I'm going to have my 12 fluid ounces of coffee and a 1/3 cup of oatmeal.

[–] JasonDJ@lemmy.zip 14 points 1 month ago* (last edited 1 month ago) (6 children)

I very much prefer to cook/bake/prep in metric grams.

2c white flour, sifted.
1c brown sugar, packed.
1c room temperature water.
2tsp active dry yeast.
2tbsp vegetable oil.
1/2tsp baking powder.
2 egg yolks.
5 egg whites.
Pinch of cinnamon.

Fuck you. Tell me how many grams that is. I don't need five different tools to measure out my ingredients. I need a wet bowl, a dry bowl, and a scale.

Also this isn't a real recipe I just started naming shit at random.

The original Fahrenheit system was actually pretty clever. It set 0° at the temperature of brine and 96° at internal body temperature. That made marking a thermometer really easy. Like, ridiculously easy. 96 is divisible by two many times before reaching a decimal.

Because the freezing temperature of water was really close to 32°, the later Fahrenheit system set that as the lower temperature and 212° as the boiling point instead of using body temperature. That made marking a thermometer more difficult, and basically took away Fahrenheit’s only advantage. It was more consistent though. Now Fahrenheit is formally defined based on Kelvin.

Centigrade was originally marked as 100° at the freezing temperature, going down as temperature increases to 0° at the boiling temperature. Obviously that didn’t last long. The downside is that marking a Celsius thermometer depended on atmospheric pressure. Now Celsius is defined based on Kelvin by -273.15° being absolute zero and a degree corresponding to a very specific amount of heat energy increase.

So yeah, Fahrenheit hasn’t made any sense for many many years.

The US could have switched to the world-wide standard years ago but under Reagan the switch was abandoned.

[–] 4am@lemmy.zip 23 points 1 month ago

No, the original “Make America Great Again” guy? The first actor elected President who presided over an unprecedented health crisis and ignored it because he hoped it would only hurt the “right” people, and plunged America into an economic disaster the likes of which we are still feeling today and may never recover from? That guy?

God this place actually sucks

We could have had it as early as 1793, but the ship carrying the metric standards was attacked by pirates.

Please also lets use the International fixed calendar where every month has exactly 28 days/4 weeks and the year has 13 months. Every 1st of the month is a sunday, every 2nd is a monday and so on, so you will always know which day it is by the number.

The leftover day is a dedicated new years day.

The one thing that bothers me about the metric system is how much of it is never actually used. No one says "1 megameter", for example. They say "1,000 kilometers". When you think about it, most metric prefixes are never used with most metric units.

Tbf as someone who grew up with the imperial system due to being raised by a British boomer its fairly easy if you're familiar with it, I still often cook in imperial due to a load of old cook books I have.

Having said that anyone who wants the imperial system in the modern day is a absolute idiot, metric is objectively superior.

[–] oxysis@lemmy.blahaj.zone 14 points 1 month ago (2 children)

While I get this is a meme, I do think the imperial measurement system deserves some credit. More the vast majority of humanity’s existence it has been an incredibly capable and powerful system. It’s only in more modern times where a system like metric is an upgrade. This is also ignoring the few ways where imperial still eke out a win, but that is besides the point.

Imperial’s weird gaps between units are pieces that come from a variety of different systems that got layered together over the centuries it lasted. 5280 feet in a mile? Based on the Roman mile which was 5000 paces from a soldier. 12 inches in a foot? From a different way people counted on their hands.

Length of an inch and length of a foot? From different parts of the body. Weird? Certainly. Practical? Amazing so. They were easier for day to day tasks and for measuring on the small, human scale. Metric is easier to calculate between different units and that is an amazing innovation.

Fahrenheit is weird today, but was more practical when it was first established. Even then it has value in how it is more granular without the necessity of decimals. Celsius is still the better unit, 0° being freezing and 100° being boiling for water is very useful. It gives you two easy to remember extremes.

Imperial had to walk, so metric could run in a way. Both systems are great in their own ways and in their own times. Imperial isn’t needed anymore, but deserves recognition for being good for its time and for being more practical historically.

The only dud metric really has is metric time, and that is because everything we have ever done has been based on the older time keeping system. Cultures have laid claim to certain dates and times of day within the old system that just have constrained us to it.

I definitely prefer metric overall, but I genuinely believe that imperial deserves more credit for getting us to the point where metric makes sense to swap to.

0 C being the temperature water freezes is useful for knowing if there is ice outside, which has practical use. If we keep going the way we are, soon 100 will be an indicator that there is no water outside. Practical if you're a hydrophobe or hydrophile.

[–] PhoenixDog@lemmy.world 13 points 1 month ago (3 children)

If you think Imperial is a better system, you're the perfect example of the American education system at work.

In case those were too many words...

You stupid.

Never got this. I saw one fucking dumb american actually defend the rrtarded system by saying "It's actually more precise" - what a fucking stupid thing to say, when you don't even have a smaller unit than freaking Inches. Atleast we have mm. You guys use 1\4 Inch. Wtf is that??
