    Good take

    I wouldn’t even be against sharing some information so they could give me better ads

    I’m not in the market for a new car. I don’t need car ads.

    But knowing I shop at Something Hardware a lot and they are having a spring black friday sale on the tool I’ve been eyeing would be nice.

    Even still Something Hardware just slapping their logo in an ad is not helpful at all.

    If ads were helpful they wouldn’t be annoying

    your freezer at -18 °C (0 °F) or lower. This will keep your food out of the temperature danger zone between 4 °C (40 °F) to 60 °C (140 °F) where bacteria can grow quickly.

    According to Canada.ca

    Every 2 F is basically 1 C. You have more whole numbers with F.

    Like -15°C is 5°F

    6°F is -14.4444°C

    -14°C is 6.8°F

    So 5, 6, and 7°F are about equal to -15, -14.5, and -14°C.

    And it’s not just a random number. You know how much more energy would be used if everyone kept their freezer just a couple degrees colder? It’s the optimum recommended temperature.

    USA uses US Customary units, not Imperial units.

    Fahrenheit is grouped with US Customary units but is not one.

    I agree metric system is superior and there isn’t a reason to use Inches, Feet, Yards, etc.

    But Fahrenheit is a great system for weather and works great for everything else.

    For science if I have to heat a beaker to 280° it doesn’t matter if it’s C or F. I’m not going to be able to relate to 280° in either system. The instrument is going to have to tell me the exact measurement.

    Same with like a tape measure. I can measure out 3 meters. I don’t need to know how long 3 meters is to do that.

    However, mark two lines on a piece of paper and I will get closer guessing in inches than cm because I know the US customary units better.

    Eventually US will change to metric. But I doubt we will ever not use Fahrenheit for normal day things like weather

    When do you use 0° and 100°C?

    This is also at standard pressure and most do not live at sea level.

    I don’t put a thermometer in my water to make sure it is boiling or one in my water to make sure it freezes.

    It can snow and roads can ice before it hits 0°C

    It has no real world applications

    90-110 is hand washing temp. 100 average.

    110 is hot

    120 recommend max

    130 very hot

    140 very very hot

    150 burns

    If I said to you. Would you stick your hand in 50°C water for 100 dollars would you do it?

    What about 60°C?

    65°C?

    I bet you don’t know what would happen if you stuck your hand in 65°C water without looking it up. There’s a huge jump from 60° to 65°C. 70°C will instantly scald you.

    Someone out there is stupid enough to think. Water boils at 100°C, 65 should be perfectly fine. Even though water doesn’t boil until 212°, most people would be cautious of sticking their hand in 100°F+ water.

    Yes if you think 40°C+ is hot then you can gather that 65°C would be hotter. But why compare to 40° when you can do 100°.

    Not sure where you got -4F from.

    USDA, United States Department of Agriculture, recommends 0°F or -17.8°C

    100°F in the shade isn’t extreme, and you’d be able to survive normally (With more water, everyone can use more water)

    100°F is hot tub water

    120°F is recommended hot tap water

    140°F water will pretty much burn you instantly

    0F is the temperature a freezer needs to be to keep food fresh.

    50F is the point that you can’t survive without clothes, your body will not generate enough heat.

    100F (38C) will not burn you alive. You can survive for a long time in a sauna at 200F.

    100F is perfect hot tub temperature

    0-150 is the better range, and 75 is right in the middle. 100 is just a hot air temperature most people don’t want to be in but it’s not an extreme.

    Saunas can get up to 200 degrees

    Hot tubs are usually at 100

    Freezers need to be at least 0

    You say 15°C. 6° cooler than room temperature. But how much is 6°?

    It’s 60°F.

    50°F or 10°C is where you need clothes to survive

    300, 325, 350 is where you bake cookies (149-176°C)

    Fahrenheit has a bunch of 5 and 10s

    Saying something like high 70s or low 70s for temp represents an easy way to tell temperature.

    21° to 26° for celcius

    I walk outside and say “It feels like high 70s today” someone using celcius would say, “Feels like 25°”. If it was a little warmer than “low 80s” compared to “Ehh about 26 or 27°C”

    Easy way to do %

    Say you want 6% of 45

    Seems hard right?

    1% of 45 is .45

    .45 × 6 =

    .4 × 6 = 2.4

    .05 × 6 = .3

    2.4 + .3 = 2.7

    So 6% of 45 is 2.7

    Extra:

    Say you want an item that is 40 dollars and it is 20% off.

    10% is 4 dollars.

    20% is 8 dollars.

    So item would be 32 dollars.
