"1 brick equals about 1kg" - Plain. Boring. No pizazz.

"1 brick equals about 37 baby chicks." - Fun. Whimsical. Oozing pizazz.

But it's really easy. Wanna know how many inches are in a mile? One inch is 0.0254 m. One mile is 1609.344 m. 1609.344 / 0.0254 is 63360. There.

But what if there are no inches in that mile, only yards? Or parsec? Oh, wait...

I'm an American and every last bit of my shop is metric. It is the superior unit of measurement in every aspect. I don't bother with imperial at all. If I have to list dimensions online in imperial, just multiply mm x 25.4 which gives me inches. That's as far as Ill go into inches and feet.

I've said this before and Ill say it again, the US was robbed of the superior unit of measurement.

Yeah but can we talk about time?

Our units of temporal measurement, from seconds on up to months, are so complicated, asymmetrical and disjunctive so as to make coherent mental reckoning in time all but impossible. Indeed, had some tyrannical god contrived to enslave our minds to time, to make it all but impossible for us to escape subjection to sodden routines and unpleasant surprises, he could hardly have done better than handing down our present system. It is like a set of trapezoidal building blocks, with no vertical or horizontal surfaces, like a language in which the simplest thought demands ornate constructions, useless particles and lengthy circumlocutions. Unlike the more successful patterns of language and science, which enable us to face experience boldly or at least level-headedly, our system of temporal calculation silently and persistently encourages our terror of time.

...It is as though architects had to measure length in feet, width in meters and height in ells; as though basic instruction manuals demanded a knowledge of five different languages. It is no wonder then that we often look into our own immediate past or future, last Tuesday or a week from Sunday, with feelings of helpless confusion. โ€ฆ

The units are complicated because our world is complicated. The moon orbits the earth in a certain interval, the earth orbit the sun and the earth revolves around itself. Those are the major points of reference but none of them line up.

[โ€“] Hamartiogonic@sopuli.xyz 12 points 5 days ago (3 children)

Best of all, none of those natural reference values are constant. They drift gradually, and lunar months wonโ€™t be 30 days forever just like a day wonโ€™t be 24 hours in the future.

Hmm, I wonder... our current standard of time might end up being the standard for a long time, primarily because of GPS. Before we had global data networks it wasn't really possible to syncronize clocks all around the world. There used to be a telephone service that you could dial which would tell you "The time is now eight fifty-five PM" or w/e because that was the most effective way to distribute a coordinated time signal, and then you could manually set your local clock/watch to match.

But GPS depends heavily on accurate time information, and keeping it accurate is very complicated. Relativitistic time dilation applies because the satellites are:

  1. far enough away from Earth (~20000km) that they experience different gravity than devices on Earth's surface, causing local time for the satellite to be be faster, and
  2. moving so fast in their orbit that they experience a measurable slowing of local time.

(that's right, using GPS on your phone is a real-world demonstration of the theory of relativity in practical effect)

..and all those satellites are constantly checking in with each other and ground stations to make sure they're in agreement.

As a result there is now a de facto standard time reference for the entire world, and all networked devices depend on it for their own timing, and it is accurate to microseconds at worst.

100 years ago people were still winding mechanical clocks every day, and setting them by the local churchbell.

The way we split them is still purely arbitrary though. We could have metric time that uses multiples of 10 just by adjusting the duration of a second accordingly and adjusting how we divide time in a day.

Days of the calendar would be more challenging. But it's still possible to make something much more workable I'm sure of it.

Have a look at the international fixed calendar, used by kodak internally until 1989. 13 months of 28 days, it looks so clean

collapsed inline mediaInternational calendar used at Kodak. Showing 13 months (Sol being a new month after June) of 28 days

Everything months starts a Sunday (I'd rather start weeks on Monday but whatever), every second Monday is the 9th. Plus it has the advantage of keeping the 7 days week we're used to. Software excluded, it looks easy to adopt.

Alternatively there was the French revolutionary calendar with 10 days weeks and 12 months

Then there's my favorite cursed unit: the kip! 1 kip=1000 lbs. "Kip" is short for "kilo-pounds." It's a unit used frequently in American civil and structural engineering. And it is so deliciously cursed.

Growing up in the Metric environment, I only have to deal with the Imperial system very rarely before the Internet. But later, I found out there's a whole country that only use Imperial, and that they almost always demand you convert your system to the one they understand, and almost never bothered with Metric when they write anything. But then again, I found out that they also use units that are totally novel. I just have to accept that this is the character of them, and continue using Metric.

[โ€“] AshLassay@lemmy.world 6 points 4 days ago* (last edited 4 days ago) (1 children)

There is no country that only uses Imperial. Americans use grams for weed. And technically what the US uses is called US Customary. Some units are different from Imperial. Funny thing is both Imperial and US Customary are legally defined in metric.

In the US, we should make things even more confusing to anger the metric folks. I propose we redefine the "foot" every four years. The length of the foot will always correspond to the actual measured foot length of the current US president.

[โ€“] pyre@lemmy.world 6 points 5 days ago (1 children)

the fact that you think this will anger metric folks who already don't make sense of your dumb system rather than ruin many aspects of your country ... uh ... never mind, you're already ruining many aspects of country. ignore what I was going to say. carry on.

One of the many failures of American public education system that I was subjected to. It's speaks volumes about how normalized exceptionalism is in this country.

"Oh, the measurement standard the rest of the world uses? You don't need to learn that. You're an American, so people from other countries will just accomodate you because they want to be like us."

One of the most annoying things in the world are American websites that claim to sell internationally but they only offer USD and all provided measurements are in American imperial.

Right up there with online stores that only have boxes for "state" and "zip code" even if the selected country doesn't use those.

Bring forth the ceremonial cudgels, it's imperial units bashing time.

The chain (abbreviated ch) is a unit of length equal to 66 feet (22 yards), used in both the US customary and Imperial unit systems. It is subdivided into 100 links. There are 10 chains in a furlong, and 80 chains in one statute mile. In metric terms, it is 20.1168 m long.

ahhh good hit, that's the stuff.

Can anyone with a deeper understanding of the history of the metric system explain why a gram is the base unit of weight, and a litre the base unit of volume?

I thought the foundation of the system was that a kilogram is the weight of a litre of water. But then why not name them 1 thing = 1 thing rather than 1000x a thing = 1 thing.

And yes I've had four cups of coffee and no sleep today.

[โ€“] viking@infosec.pub 9 points 5 days ago (3 children)

A gram is not the base unit, it started with one meter (hence, metric).

Kilo means thousand in Latin, so 1000 meters became one kilometer (aka, one thousand meters), and when they need smaller units, they took to Latin again, simply because the language was en vogue for science:

Deca (ten): Decimeter (dm, nowadays hardly used, but it exists) = 0.1m

Centum (hundred): Centimeter (cm) = 0.01m

Mille (thousand): milimiter (mm) 0.001m

Weights were then adopted from the dimensions based on practicality, i.e. one liter was a common enough volume that people could use it in a household, and it's defined by 1dm height x 1dm length x 1dm width. Or 10cm10cm10cm (same thing, but the base notation was units of one).

[โ€“] Alaknar@sopuli.xyz 8 points 4 days ago* (last edited 4 days ago)

Or 10cm10cm10cm (same thing, but the base notation was units of one).

Just FYI - Lemmy uses Markdown for formatting. In Markdown, if you surround some text in asterisks, it italicises whatever's in between.

So if you write: *this is italicised*, you get this:

this is italicised

To write 10cm*10cm*10cm you have three options:

  1. Use in-line code (what I did twice here) - surround the text in backticks (usually the ones on the left of the number 1 on the keyboard).

  2. Use "x" instead of "*".

  3. "Escape" the asterisks by adding "\" before them. You'd write it like this: 10cm\*10cm\*10cm, and you'd get: 10cm*10cm*10cm.

The big prefixes (kilo, mega, etc) are actually Greek and the small ones Latin.

First they defined the meter and then one litre was defined as one dm^3.

Thatโ€™s an interesting question that Iโ€™d never thought about before.

I asked chatGPT, which predictably bullshitted me and said theyโ€™d decided grams made more sense than kilograms for scientific lab work.

But then I searched and found this from the user tomalator on Reddit:

โ€œWhen the French were developing the metric system, they suggested the unit be called a grave (pronounced grav) being the mass of 1L of water (1000 cm3)

The French at this time being in the middle of a revolution against the rich notice that it sounded a lot like the word Graf, being a word for Duke or Earl, and they wanted to avoid affiliating with the nobility, so they changed the measurement to be the mass of 1mL of water (1 cm3) and called it the gramme

They then noticed that it was inconvenient to use a mass unit so small, so they changed back to the 1L of water definition, but kept the name gramme for the base, and threw out the word grave in favor of the kilogramme.

And that's why the kilogram is the base SI unit and not the gram. I had the exact same question when I learned the SI unites.โ€

I like metric weight for cooking (on the rare occasion I make something that involves careful measuring, and for my bread making) and MILES can fuck right off, km are fine for measuring long distance. And fine with meters, cm for short distance.

But I do like how feet are 12 inches, because 12 is so evenly divisible, and like that a gallon splits in half and half again and again until you get cups. It's like RAM,

Cup is 8 oz

Pint is 16 oz

Quart is 32 oz

Half Gallon is 64 oz

Gallon is 128 oz.

That doubling sequence is satisfying.

I want to prefer imperial, but using fractions for tools is super fucking annoying when millimeters are easy, and then stores giving me price per ounce in the store, other products price per pound making me do the fucking Mental Math multiplying times 16 pisses me off.

Fractions are a stupid way to measure small distances, and ounces are a stupid way to measure it small amounts of weight.
