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.
I just open the windows , so outside temp , wich ranges from -10 to +25 °C
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.
Thanks!
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
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
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.
Whatever the room temperature is. If I’m cold I add sheets and if I’m warm I remove sheets. Easy and inexpensive
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
I don’t care, I’m asleep.
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).
69 dude!
Yes. 20-21 is a good temperature range for sleep.
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

Celsius *2, subtract 10%, add 32.
About 17 degrees. Seems to be the sweet spot to keep my Cavalier snoring speed as low as possible without her getting cold.
~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.
- 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.
