Neat. Now use metric time. Tell me, how many kiloseconds are in a day and megaseconds in a year?
In the same way people seem to be able to learn there are 60 seconds in a minute, I know there are 12 inches in a foot.
Metric is wonderful scientifically and annoying practically. I’m with Orwell, I like a pint of beer, not 500 mL or 1 L.
Calories aren’t metric. 1 calorie is 4.184 Joules.
Also, a calorie is only 0.99857% of the energy needed to raise a gram of water (without gas dissolved in it) from freezing to boiling at 101325 Pascal of gas pressure, not 1% as the OOP states. 101325 Pascal perhaps being better known by the non-metric unit “1 atmosphere”.
This guy SI’s
TIL one gram of hydrogen is one mole of hydrogen. Neat!
Yep. Those numbers on the periodic table tell you how many grams one mole is. I think one of them is the average isotopic valie and the other is the ideal value.
The only thing that really grinds my gears with metric enthusiasts is their inability to use the system they say they love. I can’t tell you how many times I see these chucklefucks say something is “400 millimeters” when there is a fucking measurement for that. Just say “4 decimeters”, god damn double plus bad ignorant asses.
And yet for pipes and monitors it’s still inches, for deodorants it’s still fl. oz. and PSI for pressure (despite pascal and bar existing).
In Denmark? My pipes in Germany are in mm, my deodorant in ml and my bike’s tire pressure is 4.5 bar. The only things that are in inches are computer-related: Disk sizes, rack sizes and monitors. TV screens diagonals are usually advertised in cm and inches, but if you want to know which tv fits into your shelf, you don’t care for the diagonal, but for width and height, which is metric.

This is true in the US too. In fact:
Fahrenheit is good for exactly one thing: temperature for humans. It’s about the smallest difference in temperature that a human can feel. Anything 0F or below is too fucking cold for humans. Anything 100F or above is too fucking hot for humans. So instead of basing the temperature on what water does out of 100, Fahrenheit bases on how a human feels. Stupid for science, great for humans.
It’s not any better than Celsius though - you are only saying that because you are familiar with Fahrenheit.
Celsius
- 0 - freezing
- 10 - cold
- 20 - room temp
- 30 - hot
- 40 - miserably hot
- 100 - boiling
Nah, the higher resolution of Fahrenheit is simply better for measuring and communicating ambient temperatures.
The higher resolution of Fahrenheit is wasted on the absolutely subjective experience of ambient temperatures, especially when taking humidity into the equation. At least there is a feelable difference between 20 and 22 °C.
“higher resolution” does bro know what decimals are ?
No, Imperal uses fractions of whatever the fuck they are measuring lol
Nah.
I think the larger granularity is better when talking about specifically the feeling of air temperature, if for no other reason than it keeps it to whole numbers for the sake of conversation. 76f is a pretty common temperature where I live for a lot of the year. Saying 24c is technically inaccurate, that’s noticeably colder at 75f. Saying 24.4c in a regular conversation is psychotic.
We know that anything resembling knowledge in the mouth of an USian can result in bullying by the nearest jock. It’s reason enough to be afraid.
Saying 24.4c in a regular conversation is psychotic.
Doing so is accurate, which many neurodivergent people lean toward, and generally don’t appreciate being called “psychotic”, FYI. Maybe tune that hyperbole —and no, “retarded” isn’t an acceptable alternative, either.
Why stop at one decimal place then? If you want to be accurate you can probably add a few more on there. Rarely do we need even the single decimal point of accuracy though, and it adds two additional characters.
You say 24½°C, if you really need to be that accurate, but I’ve never seen anyone care about that precision in normal conversation, so we just say whole centigrade numbers…
“… and a half” is so much worse than “… point five.”
Hmm, didn’t think of that, but is there no simpler way to say that than “and a half”?
Here in German, “…und ein halb” is also technically correct, but everyone just says “…ein halb” and in my regional dialect that further deteriorates to “…a-halb”.
I guess, “point five” is sufficiently short that you might just go for that, though. In German, it’s one syllable more with “Komma Fünf”… 🫠
Agree. I will argue for this til the day I die
“my system is the best and i will never change my mind”
– person who has only ever been exposed to the one system
This assumes for whatever reasons that non-scientists could not have any reason to ever calculate anything with temperature.
If you use °C for a week or two, you’ll get used to what numbers are hot and which ones are cold. But if you ever calculate anything in imperial units for a week or two, you’ll still want to bite your table.
“Knowing things is for nerds!”

I agree, but I’m committed to the bit.
Gotta commit, or you screw the bit
Anything 0F or below is too fucking cold for humans. Anything 100F or above is too fucking hot for humans.
… Tell me you’re a privileged US resident w/o using those words. 😶
No, that’s ridiculous and arbitrary. 100 degrees Fahrenheit is already way past too fucking hot and zero is far below too fucking cold. Zero to thirty degrees Celsius is a solid cold-to-hot range. 100°C to boil water, a very common human activity, makes far more sense than 212°F, too.
100F is when I boil and 0F is when I freeze. Fahrenheit is better for outside temperature (not baking!) Metric for everything else.
