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.
I think that both the Celsius and Fahrenheit scales are now defined in terms of Kelvin and a formula. Most if not all of the units of measure are no longer related to their history except for an agreement to make the new units match the old ones at some point.
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
SRM 2387 pairs well with a cup of ISO 3103.

Cap your meal off with a NIST 1196a standard issue cigarette? I am told they taste like drywall and taxes.

Perhaps you would prefer some standard issue meat.

I wouldn’t put it past people in my country to buy it just to show off wealth :/
I have recently realized we imported the western world in the most superficial way

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.
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.
As specialized world-class lab supplies and reagents go, that is not very expensive. Stuff like pure Xe (for space thrusters) can be more by mass.
Loved reading this. Thank you!
