I don't totally understand, but I like where you're going with this. I picture a cosmological history, the rise and fall of billions of subatomic universes and civilizations, many of them consumed by their own autonomous pseudo-intelligent technologies for better or worse, which on a macro scale are behaviors of particles. We're currently working on our particle, making collective decisions that will affect the super-universe we're a part of, in a tiny but significant way.
Is this complaint just for the sake of complaining? You print out the pieces, they connect various toys together. The units could be light-years for all it matters.
There's something about the internet that makes people want to moan in public about nothing.
Whenever I see someone in a current British television show use "inches" or "feet," I'm reminded of the HN metric mafia that insists that the United States is the only place in the world that uses imperial units.
Every post/comment is selecting across 100,000+ people worldwide for the individuals most likely to complain about it.
There’s no other place on earth I can invite 100,000 people to disagree with me. Exception is maybe a public office. (Which the vast majority of people shy away from, for just this reason)
up until very recently, the only units that made it even remotely "universal" was US customary units. Or, as Arduino Vs Everyone on youtube says: "units that have gone to the moon."
Now, i speak larger measurements in metric if i think the person i am talking to understands or doesn't care; but short measurements i still use "quarter inch" or "teenth" or "thou" pronounced like "wow", from the beginning of "thousandth".
I know km, liters - i drink at least 3 liters of liquid a day, if not 4, but i drink it 1 quart beverage receptacle at a time, odd how that fits!
is it really so hard to have a ruler with both measurements? I have a ruler that lets you convert from font point to two other measurement units to inches, for page layout.
I'm american, from the '80s, and we never used metric day-to-day.
the US will be US customary units basically forever. because we're an absolutely massive geography, and there's hundreds of thousands, if not millions of mile markers, speed limit signs, "distance to" signs, speed warning signs, gas stations, etc.
So 2026 is the year where i finally say: Please, please, shut up about this. No one cares.
> is it really so hard to have a ruler with both measurements? I have a ruler that lets you convert from font point to two other measurement units to inches, for page layout.
The problem with the imperial unit system rather is that it does not form something "to build more complicated units out of".
For example: if you want inch (in) as a unit, why not have "in^2" as a corresponding small area unit and "in^3" as corresponding volume unit?
Additionally, there should be constant/regular conversion factors between the various subunits of a measure, i.e.
10^-3 km = 1 m = 10 dm = 100 cm = 1000 mm = 10^6 µm = 10^9 nm = ...
vs
1 lea = 3 mi = 24 fur = 240 ch = 5280 yd = 15840 ft = ...
we don't use leagues or furlongs. I know what a chain is because i have one, but that's specifically to measure land against a plat map. Every location in this country is based off common reference locations (there's a literal marker on the ground), with only chains and angles to delimit things (generally).
Read that last part again, because they use GPS to determine if the marker has moved, and that takes X minutes to quiesce. you can't take X*Y minutes to check each chain mark and angle.. not all land is rectilinear. we have a bit less than ten million km^2 of land in this country.
I'd reckon that maybe 1% of Americans know what a league is, as in the definition. Less for "furlong", less for "chain".
This is how these conversations go, usually. It's completely pointless, most of the people here will never interface with something where this matters. I'm a few decades old - 2.25 score years old, to be accurate. My wife knows what a score is, and how many feet in a mile, which i can never remember; by the by, it's about 5300 feet.
like Celsius, the metric measurements don't "mean" anything directly to a human. a meter is how fast light travels in 1/speedoflightinmeterspersecond. water boils at 100 and freezes at 0. compare to ~100F "roughly median body temperature", "roughly the length of an adult foot", and "roughly the length of the middle bone in your thumb".
yes, for "science" using units that convert is great, one of my favorite things to read is the Frink language unit file for that reason. Metric is cute and ostensibly "well-defined". great, use it.
you're not getting ~400,000,000 people to switch, potentially ever. The sheer cost is astronomical. a speed limit sign, just the sign is ~$22. The total cost of install could be from $500 to $3000. Per speed limit sign. There's at least 10,000 speed limit signs on interstates alone. [nearly] Every single mile of every single highway and interstate in the US has a reflective sign stating what mile it is - except for mile 420, i'm not sure why, that'll be missing but there will be a 419.7 mile marker. weird.
> In 2002, a contractor installed just over 50 miles’ worth of markers on I-78 and Routes 22 and 33 at a cost of $230,000, or about $4,500 per mile. Today, [...] $6,500 per mile, said PennDOT spokesman Ron Young.
and
> As of 2022, [...] the Interstate Highway System, which has a total length of 48,890 miles (78,680 km)
and that's just interstates. We have expressways, freeways, spurs, feeders, highways, state roads that use mile markers. Speed limit signs vary in distance, but figure 2 miles per (raelly 1 per mile since they're on both directions of travel, and usually there's 2 per direction, one on either shoulder) on nearly every commute surface. we have ~2,600,000 miles of paved roads, and a bit over 4,000,000 miles of roads, total, in the US - that's 6.437376e+6 kilometers, or 21 lightseconds in a vacuum, or 32 lightseconds in fiber optic cable. 32000ms ping, awesome.
Every house in the US is built with 16" on-center framing for the walls. we're not going to switch to "406.4mm on center", because our sheetrock, plywood, etc are all 48"x96".
every other country that switched did it 70+ years ago, has less people, or is drastically smaller.
like i said, rudely, but now politely, give it up, we're staying with our US customary units.

The same holds for more obscure unit prefixes in the SI system like dam (decameter) or hm (hectometer) in the SI unit system (as far as I am aware, the only common usage of the "deca" prefix is in Austria for "decagram" (dag)).
Nevertheless, even these obscure units fit the regular pattern perfectly:
I forgot one thing. you said "why not have in^2 and in^3" we do, but we don't use that very often. Older American "muscle cars" engines' displacement was measured in cubic inches. every child learns what a square inch is. a "board foot" is 12 cubic inches of milled wood, 12 in^3 - I don't know how to verify this on a Sunday, so this may be wrong, the board-foot. And then, we use square feet; for floor space in a house, say, my house is ~1500 ft^2. We also use cubic yards, yd^3, for stuff like dirt, concrete. when talking about this, like if i need a driveway's worth of concrete, the load is measured in "yards" which is short for "cubic yards."
But all that aside, and with apologies to mods and you for sneering; i wanted to say this in my prior reply but when reading it aloud to my wife i took it out:
Americans can, in general, divide and multiply by numbers other than 10.
yes, we use acres and hectares, too! it sounds better to say i live on 6.5 acres to an American neighbor who asks, than 0.02630457km^2...
edit window closed but i wanted to say that i like that metric units are all related. 1cc of water is 1ml is 1g. that's lovely, and pretty, in the sense that Carl Sagan would use it.
Doesn't mean the USA has to switch for common use.
I've been cooking for something like a quarter century, for multiple people, and i have never once, in my life, used a kitchen scale. I have one for doing METRIC measurements of ratios of liquids for other uses, but not once for cooking.
A stick of butter is a quarter pound. it doesn't matter though, because the butter is marked in "recipe increments". if you melt it, you can use "tablespoons" to measure it, literally.
eta: i haven't even used measuring cups or spoons for anything in like a decade, unless i am making bread or bread-like things.
Found a copy of the book on Wikimedia. It was originaly published as a pattern book for kimono textile, then rediscovered in 1986 in a collection at the Boston Museum. Since then art historians in Japan found further prints.
Comments like this is proof that the old-school hacker spirit is alive and kicking. This kind of pride in efficient and artful use of computers is needed more than ever.
This is taught in graphic design, how people typically scan information from left to right and top to bottom, in cultures where the written language flows in that direction. However, a counter argument could be made that people perceive paintings differently from the way they read written text. There have been studies about how the Japanese perceive images and sounds with the same area of the brain that processes language, in contrast to other cultures where they're processed separately.

That "Big Wave" variation with birds flying over the waves is strikingly beautiful. So dynamic and raw compared to the famous one. And how poetic the shapes of birds rhyme with the shape of waves. I'm gonna have to set aside some time to appreciate Hokusai's works again. Lovely.
I don't know whether Escher was familiar with Hokusai's work but they shared a common interest in tilings and tesselations. Damned if I can find those Hokusai sketches on the web now.
Wow that is kind of mind-blowing. Looking through other pages, Hokusai is showing each "rule" (法) and its application (tessalation) that produces the pattern. It makes me wonder about what kind of cultural exchange was happening between Japan and Europe at the time.
Escher would be generations younger. However, I am curious about whether Hokusai encountered any Islamic art. Tesselations and symmetry play a big role in that one. I submitted ed this link as a separate HN post.
