Actual poster from 1917 that made me laugh. A lot.

Also, those motherfuckers are measuring the weight of those balls in kilograms, aren’t they?

Imperial US system is defined using the metric system…

The US Government is entirely metric. It’s just the US Citizens that aren’t. So there’s this entire separation where no one uses metric, so nothing is made for metric, since nothing is made for metric, no one uses metric.

Obviously that’s changing over time plenty of people use a mixture of both systems all the time. The machines are mostly driving adoption at this point. 3D printers, cars, etc.

1l of (4°C) water weighs 1kg. 1kg (of anything) is 1000g. 1g of water is 1cm³. Stack 1000 1cm³ blocks to get a 10m high column. This column exerts 100kPa of pressure on its base. To heat it by 1°C requires 1kcal. And 1N would accelerate it by 1m/s every second.

I’ve posted this before on my mastodon, and on feddit.de, before the instance was shut down, but I think it’s still a nice showcase how SI units interact with one another.

The worst thing we have in the metric system is kWh/1000h. It’s just watts, but whoever designed the energy labels thought a bunch of zeros would be funny or something.

I’ve heard that kWh/1000h is used as a power rating for light bulbs, because if they just wrote it as watts, people might confuse it with a brightness rating (e.g. “this LED bulb produces as much light as a 100W incandescent bulb”)

The kWh/1000h does convey more information than just W though. If I buy a fridge and it says 100W I wouldn’t know if that’s its max power draw or average over time. With the 1000h in there it’s pretty clear we are talking about the average.
Also people who aren’t technically minded might only know “kWh” as that’s what it states on your power bill and they can directly guess what kind of energy bill this fridge might cause.
So you are technically correct I guess and we all know that’s the best kind of correct.
We do have worse stuff in the metric system though, kcal is not the same as the SI for energy (J) for example. Also everything involving time gets messy quickly. Nothing compared to the imperial measurements obviously

Wouldn’t the second one make more sense as an upside down pyramid?

Because the first digit in each of the numbers is larger than the second digit it would be the triple inverted pyramid as shown, where the larger numbers correspond to larger sub-pyramids and larger digits correspond to the larger side of the sub-pyramid.

The colored text and marks on the pyramids are to show that.

I believe in some countries in the world, the year goes first, then the month, then the day (2024/08/08 or 2024, August 8). Seems more logical to me than the literal inverse (08/08/2024 or 8 August 2024).

But yeah, the metric system reigns supreme.

I would’ve mentioned it but I forgot what it’s called. Thanks for reminding me.

Year, month, day is the most logical. I’ll stand by month, day, year as being more logical than day, month, year because it’s somewhat more sorted lol.

How in the world is (month/day/year) more sorted than (day/month/year)? I see two use-cases: Sorting things chronologically, in which case you want YYYY/MM/DD, or referring to nearby dates, where the year or even month can be assumed known implicitly, in which case you use DD/MM/YYYY. In no sane world does MM/DD/YYYY make sense.

I mean, I’m fine with the long form (August 8, 2024), but definitely not the short form, which today looks indistinguishable from DD/MM/YYYY anyway. I often think it’s the other way around and ask “since when was there a 26th month??”.
