You want numbers to be understandable and K produces illogical numbers. (There is a reason it is common to drop the century when talking about years, humans are less skilled at numbers over 100) And I know temperatures in Fahrenheit go higher but it is common to refer to Phoenix as "over 100" even when it's high can peak over 120.
That’s 02025 thinking.
(I'm a little sad the five-digit date hasn't become popular.)
A US gallon of deuterium water costs roughly $2,600 to $3,800, while a gallon of pure tritium water (super-heavy water) would cost about $44 million.
How much volume is that for the rest of the world? Really unscientific article.

this is actually why i like fahrenheit the most... 0F is "really cold" and 100F is "really hot", whereas in celsius 0C is "kind of cold" and 100C is "uninhabitable". it makes sense for the 0-100 range to be reserved for temperatures frequently encountered in our habitat as humans i think...
That’s a biased view that leads to a scale only convenient for people living in particular latitudes. Now talk to someone living near the equator like Singapore, and 0F is unimaginably cold (even 40F is basically unheard of), and 100F is very hot but not extraordinarily so. Then you talk to someone living close to the arctic and the converse is true. All this talk about 0F to 100F being frequently encountered probabl…
I mean, the other option is cool vs dead

The second most diverse range of temps in the world is smack dab in the middle of the US: South Dakota up through northern Minnesota. Most years that area experiences -40F in the winter and 110F in the summer.

Except 0F being “really cold” and 100F being “really hot” is a personal bias of yours based on where you’ve lived. It’s not true for everyone or everywhere. And even if it were true, it still wouldn’t work. 100F in a dry environment is nice while, in a humid environment, 100F is awful. Same for 0F, a dry and static 0F is fine while a wet and windy 0F is killer.
How does the water taste?

With all of those examples, the actual temperature doesn’t really matter. For drinking and bathing, people go by feel. In the kitchen, the freezer makes water freeze, and the stovetop will make it boil into steam, but exact temperatures aren’t really relevant here either. The same goes for ironing clothes, the iron just does it. When I think about where explicit temperatures are needed in the home, the oven and therm…
> When I think about where explicit temperatures are needed in the home, the oven and thermostat are the two things that come to mind. But in that case in what way is for example baking a frozen pizza from the store at 400 to 425 degrees F more relatable/convenient/natural than 200 to 220 degrees C?

Truth. I once paid nearly $500 for a set of 17 certified, calibrated wooden pencils, with documentation showing that each one met their rated hardness levels of 9H thru 6B. And for $500, they don't even come with erasers, that is an added-cost option. https://www.gardco.com/product/pencil-hardness-test-kit-astm...
Can I ask why :-) Sounds like an interesting project.
> For the pencil hardness test, reference ASTM D3363, pencils of increasing hardness values are moved over the surface in a precisely defined way until one lead damages the surface. Surface Hardness is defined by the hardest pencil grade which just fails to damage the surface.
> Observe the pencil track. Sufficient pressure must have been applied either to cut or damage the coating or to crush the lead pencil point.
> If neither coating damage or pencil point crushing is observed, repeat the test until a definite observation is made.
> If scratching or damage of the surface occurs, proceed with the next softer pencil grade and repeat the testing process until a pencil lead grade is found which crushes and does not damage the coating.
> If crushing of the hardest lead should occur, the coating is therefore extremely hard and is beyond the measuring range of this test
