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

[–] harmbugler@piefed.social 1 points 1 month ago (1 children)

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

[–] glups@piefed.social 0 points 1 month ago

I had to look it up, TIL blood boils at the same temp as water

[–] MissJinx@lemmy.world 0 points 1 month ago (1 children)

As a woman I also only take 100ºC showers

[–] Mok98@feddit.it 1 points 1 month ago (1 children)

Any hotter wouldn't be a shower anymore, would it?

should be french flag because the metric system originates from france and now its used everhwhere except myanmar, us and liberia

[–] Knightfox@lemmy.world 0 points 1 month ago (1 children)

Kilometers to miles is probably the easiest common conversion. 5 km is 3 miles, easy peasy.

[–] ReluctantMuskrat@lemmy.world 1 points 1 month ago

Except 5km is not 3 miles... it's 3.1069 miles so off by a considerable factor. 1 mile = 1.6km is a much more accurate approximation that's easy to remember.

[–] glitchdx@lemmy.world -1 points 1 month ago

A mile is 8 furlongs.

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.

[–] elephantium@lemmy.world 1 points 1 month ago

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

[–] DahGangalang@infosec.pub 1 points 1 month ago (2 children)

100 warm

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

[–] IAmNorRealTakeYourMeds@lemmy.world 0 points 1 month ago (1 children)

That's how I like my showers

[–] FrChazzz@lemmus.org 0 points 1 month ago (1 children)

I didn't know my wife had an account on here! Hey, babe!

Heyyyy. it's not cheating if you think I'm your wife.

[–] Soggy@lemmy.world -1 points 1 month ago

On a cosmic scale 100C is practically freezing.

[–] damnedfurry@lemmy.world 1 points 1 month ago* (last edited 1 month ago) (1 children)

212 warm / 100 warm
warm

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.

[–] Wispy2891@lemmy.world 1 points 1 month ago

I think I never saw using Deca- and deci- in real life

[–] bilb@lemmy.ml 0 points 1 month ago (1 children)

I've thought that was weird too. Decimeter's seems like a good unit for measuring a person's height, for instance.

[–] lord_ryvan@ttrpg.network 2 points 3 weeks ago (1 children)

Idk I prefer 174 cm over 17.4 dm. 17 dm is not nearly precise enough, either.

[–] bilb@lemmy.ml 1 points 3 weeks ago* (last edited 3 weeks ago)

Yeah, I hear you. There's really no practical difference between saying 174cm and 17.4dm I think from the American perspective where 6ft is a sort of benchmark for adult male height, so psychologically that 6 looms large. CMs obviously work fine, but I'm trained to see the bigger 17 as a sort of benchmark/goal. None of that is healthy or rational, though.

Maybe it's easier to say "Oh, they're 17dm" or "15dm" and get a general sense for the height of a person. When you need to get precise, it's not useful.

C is even more intuitive than the graphic.

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

[–] lord_ryvan@ttrpg.network 2 points 3 weeks ago

Also…

  • 30 is hot
  • 20 is nice
  • 10 is cold
  • 0 is ice
[–] Soggy@lemmy.world 1 points 1 month ago

*at sea level, assuming pure water

It's intuitive with respect to water. Applying it to anything else is exactly the same as the Fahrenheit scale: you associate various things with numbers.

[–] rayyy@piefed.social 0 points 1 month ago (1 children)

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

[–] 4am@lemmy.zip 1 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

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.

[–] neidu3@sh.itjust.works 1 points 1 month ago (2 children)

A brit once told me that the imperial system makes sense if you look at it from the perspective of a peasant at the market - units of 12 was a lot easier to work with in the olden days because it's easily divisible by 2, 3, 4, and 6.

I guess it makes sense from a historical viewpoint.

[–] seejur@lemmy.world 1 points 1 month ago (1 children)

I just wish it was always 12 instead of 3, 12, 1760 and whatever the eff they come up with.

Farenheit on the other hand does not make sense at all

[–] Geologist@lemmy.zip 0 points 1 month ago (1 children)

Best way to use Fahrenheit is to consider it as a percentage of how hot it is. 0 degrees is zero percent hot, and 100 is fully hot. Beyond that you’re in super cold/hot territory.

But yeah, Celsius is still better.

Imperial is FAR more human and "natural" then metric. Metric fails frequently at being quantifiable with natural experiences and objects.

But imperial falls apart the second your trying to do something at a large scale, super small scales or literally anything that isn't "human scale"

And basically every test I've ever seen. If you don't have tools or some reference point, people will nine times out of 10 be able to more accurately gauge something using imperial measurements then using metric measurements.

Metric relies far too much on reference in tooling, but that's also its greatest strength. It's absurdly, exact and reliable while imperial is loosey-goosey

[–] markz@suppo.fi 0 points 1 month ago (2 children)

Yeah, 100°C is pretty warm

[–] hemko@lemmy.dbzer0.com 0 points 1 month ago (1 children)

0°C = outside the sauna

100°C = inside the sauna

[–] markz@suppo.fi 1 points 1 month ago

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

[–] blinfabian@feddit.nl 0 points 1 month ago (1 children)

yup, i take baths in 100C regularly bc its warm :3

[–] Saapas@piefed.zip 0 points 1 month ago (1 children)

Well if sauna is considered a bath then yes

[–] testfactor@lemmy.world 1 points 1 month ago (1 children)

The sauna you're in is 100°C? 212°F? I think you might be dead bro.

[–] hemko@lemmy.dbzer0.com 0 points 1 month ago (1 children)

Sauna temperature is usually around 80-100°C, depending on your preference.

World Sauna Championship starting temperature was 110°C

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.

Sounds fun, now update every computer system simultaneously to a new date format.
