Cap your meal off with a NIST 1196a standard issue cigarette? I am told they taste like drywall and taxes. https://www.nist.gov/news-events/news/2020/02/nist-releases-... Perhaps you would prefer some standard issue meat. https://www.sigmaaldrich.com/US/en/product/sial/nist1546a

It's only $508 per cigarette: https://shop.nist.gov/ccrz__ProductDetails?sku=1196a&cclcl=e...

400 cigarettes actually! Not too bad.

That’s $508 for two cartons for 400 cigarettes total, so $1.27 per cigarette. They’re not characterized like the peanut butter, they’re just manufactured to a specific QC standard.

California/New York prices are easily $0.75/cigg so it’s not that much more expensive.

This is why we should ditch Celsius for Kelvin. I never liked how we coupled 0 and 100 to where water freezes and boils under certain conditions. Kelvin doesn't rely on non-invariant reference points.

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...

OF will still kill you faster than 100F, and most folks aren't comfortable at 50F.

It inspires the following idea: A nonlinear scale where ~72F is 0, and +X represents the same level of heat discomfort as -X represents cold discomfort.

Nothing screams freedom more than using ancient terms like horsepower and measuring tires in inches and percentages. The other day I heard an American talk about a TV being 65 inches. Took me a while to understand they had a 165 centimeter diagonal television.

I bet you’d use lightyears over petametres or exametres though.

It's more typical to use parsecs in practice for astronomy.

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 probably reveals your local climate conditions more than it helps define a useful global standard for all humans. We should accept that humans live in more diverse conditions than we intuit and such a scale probably won’t be useful for all.

This has always been my primary argument in favor of Fahrenheit. It makes sense for humans, which is all a majority of the population really cares about. In addition, it's more granular. Sometimes turning the thermostat up or down by 1C could be too much, where 1F is just right. In science and math, I can see where having round numbers for commonly used temperatures would be useful, but if 0C and 100C are the only pl…

Celcius is pretty intuitive actually. It takes atmospheric pressure into account, Water is pretty abundant on the surface of the planet, and life kinda depends on it. It's a remarkable substance and quite stable. I dont think theres another substance where we can see all three phases with kitchen appliances and still consume it. Equally good for bathing and drinking. I need steam to clean clothes and cook my food. Using water as a benchmark for how we measure temperature is remarkably useful.

Kelvin does still rely on each degree being 1% of the way between freezing and boiling so it kinda does rely on a variant reference point

The reference point is the triple point, and invariant.

Sure technically yes, but also celsius is now technically defined as just Kelvin plus 273.15. Degrees have technically been redefined as exactly 1.380649×10^−23 joules

Reminds of me of the "most expensive peanut butter" at ~$2.44/g - sold by NIST, I assume for some sort of peanut butter factory process calibration: https://shop.nist.gov/ccrz__ProductDetails?sku=2387

Yes, it’s a bit frightening to know what a hidden dependency NIST is on many things. In my industry, all calibrations ultimately derive from physical NIST standards for resistance, frequency, etc.

A suggested product is "domestic sludge", lol. This is such a fun rabbit hole: https://www.sigmaaldrich.com/US/en/product/sial/nist2781

Pretty much every process conducted at scale will have such reference samples.

Now I'm imagining some kind of timezone-like temperature unit that varies around the world, and a "100 things programmers should know about ___" post about all the intricacies and special cases.
