  • If the 300m people lived in the same area and you got a true random sample.

    Sunsets at 9:09 today in Michigan

    Sunsets at 8:04 today in California

    Sunsets at 8:34 today in North Carolina

    Sunsets at 7:57 today in Alabama

    Sunsets at 7:38 today in Arizona (They are on standard time)

    Sunsets at 7:13 today in Hawaii

    Sunsets at 11:36 today in Alaska

    Someone in Arizona might want the sun to set at 7:38. It’s blazing hot all day.

    Someone in Michigan might be fine with sunsetting at 8:08 with standard time.

    Someone in Alabama might not want the sun to set at 6:57.

    Someone in Hawaii probably doesn’t want the sun to set at 6:13.

    Even if you split up the 1000 people to equally represent all states, that’s only 20 people per state.












  • There are the “I like to keep my house at 66°F because I like to wear a hoodie or use a blanket”. They are going to say that 75°F is warm or even hot for a room.

    If an average person sat naked in a 75°F room they would be happy.

    68°F or 20°C is cold for me. Even 70°F or 21°C. I keep my house around 72° to 74°F and bump it up or down a degree. Coming in from mowing the yard, bump it down, sitting all day watching movies, keep it the same, cold winter day, bump it up.

    Older people keep their houses at 78°+

    100°F doesn’t mean “not fit for human habitation”

    Anything above body temperature of 98.6°F (37°C) you are slowly cooking yourself. That’s why 100°F is important.


  • Might be popular in new expensive builds

    Standard house isn’t going to have them

    Really I don’t see much of a point for one. Crappy house with crappy plumbing, but they aren’t going to buy a fancy valve to make the problems somewhat manageable.

    Tankless water heaters are becoming more popular. The thermostatic valve would save you from turning the standard water mixer a little hotter when you run out of room temp cold water in the lines and the cold water from outside reaches the shower. Otherwise, you are always being supplied constant temperature water.

    I feel like most people that would be willing to pay extra for a thermostatic valve would pay extra to have an oversized water heater, or even tankless.


  • Yeah, they can weigh up to 2000lbs with a king-size bed. A king-size bed is 6,080 sq in.

    A fridge can weigh 300lb being 36"×30". 1,152 sq in.

    Fridge is .26 pounds per sq inch. A water bed is .33 pounds per sq inch.

    So while heavy the weight is distributed basically like a fridge. This is assuming an empty fridge.

    As for durability, a quality waterbed mattress is thick. You aren’t going to pop it or cut it without deliberately trying to.

    Even if you took a knife and stabbed it from the top, it’s not going to leak until you put weight on it.


  • 50°F is the point where you need clothes to survive. If you sat naked in a 50°F room you run the risk of your body not being able to generate enough heat and you’ll slowly die.

    ~75°F is room temperature. It’s in the middle on the warm side.

    70°F is a cool room, 80°F is a warm room.

    Whenever I think of Celsius I see it as 0° to 40° with 20° being room temperature. I hear 30°C and think halfway between 70 and 100 so I know it’s around 85°F and I know how 85°F feels.

    But like 35°C. That’s 3/4 of the way from 20°C to 40°F. 100°F-70°F is 30°. 3/4 of 30 is 22.5. So 35° must be close to 70°+22.5° or ~93°F. I know how 93°F feels.

    I can see how celcius is easier if you learned it as a child. 35°C would just be 35°C. But trying to quickly wrap your head around it is difficult unless you just know it. I’m sure if I said 93°F you could tell me that that is pretty hot.


  • You never deal with 0°C/32°F or 100°C/212°F unless you’re in a science lab.

    They are nice numbers in celcius, but for real-world applications, it’s almost meaningless.

    When I boil water on the stove, I don’t check if it hits 100°C. When I freeze water in the freezer, I don’t check if it hits 0°C.

    Everyone can get by without knowing the exact degrees.

    This is pure water at standard pressure. Higher or lower altitudes will change it, and if your water has minerals or impurities in it, it will also change it. It’s pretty arbitrary.

    Water on roads can freeze before it hits 0°C outside. It can even snow above 0°C.

    Fahrenheit is a very simple scale other than those two things. <0° extremely cold, >100° extremely hot for air temperature. Freezers are 0°F and Saunas are 200°F. Hot tubs are 100°F. You bake cookies at 325° to 375°, pizza is cooked at 600° to 800°F. You’ll find a lot of 25° increments in cooking.

    Fahrenheit isn’t really a part of the US customary units.

    Knowing both Fahrenheit and Celsius, I do think Fahrenheit is simpler for real-world applications. For science they are just numbers on a scale. Converting is the only real problem.
