16-18C is probably best. Love curling up in the duvet in the cold, but cold normally means damp too ☹️

Sleeping above 25C is miserable.

If you don't need to be super accurate:

  • C to F: double then add 30
  • F to C: subtract 30 then halve it

I like the room cold for sleeping. 60F (15C) is ideal, but we can't get that cool in the summer.

I just open the windows , so outside temp , wich ranges from -10 to +25 °C

[-] [email protected] 8 points 1 month ago

The easiest way I find is to memorize the 0/10/20/30C to F conversions, then plus/minus at 2 to 1 from there.

32 = 0 50 = 10 68 = 20 86 = 30

70F is ~21C, 54F is ~12C, 81F is ~27.5C.

This comparison makes Celsius look even harder to use hahaha.

Only 10 degrees between 68 and 86? That's either a very nice but chilly day or a hot day

[-] [email protected] 4 points 1 month ago

Where I grew up it was between 20 and 30 much of the year. Honestly a 10 point warmness scale is quite easy to adjust to.

I have heard farenheit defenders point out that we're not water - that farenheit cares about the temperatures that humans care about

[-] [email protected] 1 points 1 month ago

We are not water.

But the weather is.

[-] [email protected] 2 points 1 month ago* (last edited 1 month ago)

"The Weather" has never come close to 100C. "The Weather" is rarely below -17C and rarely above 37C: 0F to 100F

"The weather" makes far more sense in F than C.

Cooking makes sense in Celsius. We are regularly concerned about freezing and boiling when we are cooking.

[-] [email protected] 2 points 1 month ago

I'm born and raised in the US, so I grew up on Fahrenheit, but switched my phone to Celsius about 10 years ago because I wanted to better understand the scale and have stuck with it ever since. I really don't need to know the exact temperature when I check the weather, just an estimate of whether I should dress for "hot", "cold", or "mild". One of the "tricks" I heard early on was similar: 0°C is freezing. 10°C is cold. 20°C is comfortable. 30°C is warm/hot. 40°C is fucking hot.

[-] [email protected] 1 points 1 month ago

I can honestly say that I can only tell apart differences of 1 °F in the context of pools. With air temperature there's humidity, wind, and sunlight that all contribute to the experienced temperature in ways that can make two 68 degree days feel entirely different.

[-] [email protected] 5 points 1 month ago

Whatever the room temperature is. If I'm cold I add sheets and if I'm warm I remove sheets. Easy and inexpensive

[-] [email protected] 5 points 1 month ago

I usually set the thermostat to 28c or so, but I doubt it gets there, I get a sore throat at night if it's cold and I end up being miserable and spending way too long in bed the next day.

[-] [email protected] 7 points 1 month ago

What are you a lizard? 28c?

[-] [email protected] 2 points 1 month ago

Yeah? I'm not moving when I sleep so I need to get heat somehow.

[-] [email protected] 1 points 1 month ago

Right now I have it at 24c and that's comfortable. During peak summer I have it set to 26c and I wish I could go a little lower...

Uff. 28c sounds tough. How do you sleep? I wake up sweating without any blankets at 26c. Do you have windows open? Fans?

It goes as low as 10°C / 50°F in winter. I've programmed the radiator valve to give some heat (14°C/57°F) before going to bed and waking up. We have 2 duvets with flannel sheets, and a fleece bedspread on top. Today it's 17°C/63°F. Just one single duvet, time for regular cotton sheets, flannel ones are getting uncomfortably warm. As soon as it's about 10°C outside we'll leave the window open all night. We have a large frame with a mosquito screen and live in a very peaceful neighborhood. For summer, just a cotton sheet, that will probably be left down the feet most of the time. On holiday with sometimes 30°C the whole night, we basically cannot sleep, the confortable limit for us is close to 26°C - but it's more related to humidity than temperature

[-] [email protected] 4 points 1 month ago* (last edited 1 month ago)

The two formulas are:

F=(C x 1.8)+32

C=(F-32)/1.8

If you think about the formula for converting, it's close to multiplying or dividing by 2. This step is off by about 10% (1.8/2=0.9). So converting from F to C, subtract 32, divide by 2, then add 10%.

For C to F, multiply by 2, subtract 10%, then add 32.

At typical temps, I've found this is usually within a degree, and easy to do in my head (and I have zero working memory).

[-] [email protected] 4 points 1 month ago

Fractions...

10C* (9F/5C) + 32F = 50F

Or

10/5=2, 2*9=18, 18+32=50

If you stick to multiples of 5 it's easy:

0C - 32F

5C - 41F

10C - 50F

...

30C - 86F

35C - 95F

40C - 104F

[-] [email protected] 3 points 1 month ago

68F in the winter, 72F in the summer

I’d personally go lower in the winter, but the rest of my family disagrees

[-] [email protected] 2 points 1 month ago

Exactly the same for me.

[-] [email protected] 2 points 1 month ago

I do 65F in winter and 72-75 F in summer... but I hate paying electric bills...

[-] [email protected] 3 points 1 month ago

In a country where thermostats and air conditioners and whatever in your house isn't really a norm. So like other answers here, just whatever temperature. And I adjust the amount of layers on my bed or that I'm wearing to accommodate. Hot summer nights are the worst.

[-] [email protected] 3 points 1 month ago
  • 0°C is freezing
  • 10°C is cold
  • 20°C is comfortable. Roughly "room temperature"
  • 30°C is warm/hot
  • 40°C is fucking hot

Depending on a variety of factors, I generally like my space to be 18-22°C during waking hours, and maybe 16-20°C for sleeping.

[-] [email protected] 3 points 1 month ago

I'm knocked out at anything above 27 and uncomfortable living in a 16 degree room. I don't know how people are able to handle some of those extreme temperatures

[-] [email protected] 3 points 1 month ago

About 17 degrees. Seems to be the sweet spot to keep my Cavalier snoring speed as low as possible without her getting cold.

[-] [email protected] 3 points 1 month ago

I don't care, I'm asleep.

[-] [email protected] 3 points 1 month ago

~18C but I also like it much colder, but it hardly gets any colder in my bedroom because my partner is always freezing. In summer it's really hard for me, above 22C is uncomfortable.

[-] [email protected] 3 points 1 month ago

Celsius *2, subtract 10%, add 32.

[-] [email protected] 2 points 1 month ago* (last edited 1 month ago)

25-25.5° With no fan running, up to 26 with a fan running

[-] [email protected] 2 points 1 month ago

Around 17°C in the winter, as cool as I can reasonably get it in the summer, usually about 27°C

[-] [email protected] 2 points 1 month ago

About 65F to start with, then just before I get into bed, I turn off the heater, because supposedly you sleep better when reasonably cool.

The other comment is right, hot nights are the worst.

[-] [email protected] 2 points 1 month ago

Heating and cooling are expensive at our house so we generally let the temp do what it wants so long as it stays between 64F and 80F. The dehumidifier, though, tends to keep it in the upper end of that range during the summer.

[-] [email protected] 2 points 1 month ago

Whatever temperature the apartment ends up at 🥲 My cat won't sleep with the windows closed (insane behavior), and I'm not running heat or air with them open.

My ideal is 68°F or around 20°C, but kitty gets whatever she wants.

[-] [email protected] 2 points 1 month ago
[-] [email protected] 2 points 1 month ago

I'd like to keep it at 15, but my room refuses to cool down any further than 20C even with the window open.

[-] [email protected] 1 points 1 month ago

I don't know but it's too hot for me and too cold for the wife. A perfect compromise.

[-] [email protected] 1 points 1 month ago

Most of the year I just leave the window open. But in peak winter/summer I keep it around 21/19 respectively

[-] [email protected] 1 points 1 month ago

I keep it at 68 or 20. The easiest way to convert is to take 68 add 100 multiple by 37 then divide by 188.4.

[-] [email protected] 1 points 1 month ago

It varies by season. In summer, typically 24 on 'dry' mode to pull out as much humidity as possible. In the winter, on nights that fall below 16 (Japanese homes have shit insulation), I'd set the heater to somewhere between 16-20 depending upon how cold I felt on that particular day. These days (spring), we're not using anything at night, really.

[-] [email protected] 1 points 1 month ago

I'd prefer something like 68-70F (20-21C) at night, but something more like 73-75F (23-24C) in the day

[-] [email protected] 1 points 1 month ago

28°c if possible, it's been 29/30°c high humidity recently.

Equator, nothing much we can do.
