    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.

    ~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.

    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

            “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.

        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.

        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.

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

    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

    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 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.

      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?

        No, I wouldn’t heat with the windows open. All windows are shut. I don’t sweat in my sleep and usually sleep under a thick blanket. I’m just terrible in the cold.

        I’m technically originally from Russia but summers where I was are like 30c+ and in the winter it’s usually very toasty indoors. It’ll never not shock me that Europeans tolerate such cold indoors, especially the UK which due to the wind and humidity feels colder in spring than eastern Europe in deep snow winter.

    • 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.

    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).

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