Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

I generally agree that metric is better, but there's an argument for Fahrenheit.

It was based on human body temperature, so its easier to inuit if a temperature "feels hot"

[–] [email protected] 16 points 5 months ago (1 children)

How? it is just numbers, there is no human relation. i grew up learning both measures. i know that 20C is comfortable the same at 68F is comfortable. If anything C makes more sense, at 0 things are going to want to freeze on my body. For F that is 32...an arbitrary value

[–] [email protected] 3 points 5 months ago (1 children)

IIRC the original reference temperatures for Farenheit were ice brine (0°) and human body temperature (100°).

Nowadays it's formally defined in relation to Kelvin.

The ice brine was actual a unique solution the guy establish to freeze at zero, not saltwater like I was originally taught, so it was completely arbitrary 0. And the body temp for normal people is 97.5 to 98. It feela like the dude wanted a 0-100 scale and tweaked the whole thing to suit his desire.

0-50f is cold enough to kill you by exposure, 75f is comfortable, 100f is uncomfortable, higher than 100f can kill you. Seems kinda arbitrary to me.

[–] [email protected] 7 points 5 months ago

Sounds like it goes from "can kill you" to "can kill you". Kinda important milestones

[–] [email protected] 3 points 5 months ago

75 F is not comfortable at all, 80 F is deadly, 170 - 200 is fine as long as it's about 400% rel humidity and in a wooden room

Kind regards, a nord

Can't that be done with the Celsius scale as well? If you think about it..

[–] [email protected] 14 points 5 months ago* (last edited 5 months ago) (2 children)

Sure. Kelvin is the proper scale. Celsius is just water from freezing to boiling at some atmospheric pressure divided into 100 units. Not because there's anything absolute to it, but because water is kind of important in our lives.

[–] [email protected] 6 points 5 months ago* (last edited 5 months ago) (1 children)

Exactly. I once visited a seed bank and there was some text along the lines of “we store these seeds at -60 °C which is 3 times as cold as your typical freezer” (for Americans: a freezer typically is about -20 °C). Yeah, no, that’s not how it works. With Kelvin you can actually do math like that, because 0 K is ~~the absence of heat~~ zero thermal energy.

[–] [email protected] 6 points 5 months ago

0 K is zero thermal energy, not heat. Heat is the amount of thermal energy transferred during a process.

Like being the majority of our bodies!

[–] [email protected] 8 points 5 months ago

Everything can be done with the other scale if you're willing to think about it

[–] [email protected] 0 points 5 months ago

Sure there's an argument, but it's a terrible one and you should feel bad for even making it
