Technically the metric system is "the preferred system of weights and measures for United States trade and commerce" as per the Metric Conversion Act of 1975.

You're just also allowed to use lbs and feet and stuff and most people do.

Screw that, we'll make them use Metric. BY FORCE!

And in the sciences and drug dealing and the military, we use metric exclusively.

But for some idiotic reason, construction engineers often use imperial units and I have no idea why. Like buildings are built in pounds and feet and stuff, with half inch bolts and 2x4 (ish) lumber and half inch plywood. It’s idiotic.

[-] randomwords@midwest.social 0 points 1 year ago

I don't generally defend imperial, but feet and inches are actually really useful in construction. Base 12 is easily divisible by 2, 4, and 3. You often need to divide architectural elements in thirds.

[-] GrumbleGrim@discuss.tchncs.de 1 points 1 year ago

As a former structural engineer who lived on a Jobber 5 all day, that's still pretty niche overall. Easier because it's what your used to maybe, but outweighed by situations where it's not. Try doing trig with fractions and then tell me imperial is better.

Does it matter whether you punch 3/8 or .375 into a calculator? Don’t tell me you calculate stuff by hand…

That might be somewhat useful if it was consistently applied, which it is not.

And it’s maybe useful for fractions, but how many feet are in a mile again? 5280? A square yard is what now… 1296 square inches?! Who the fuck is supposed to memorize all that?

What’s a 1/4 square yard in square inches?

That’s not easy, that’s putting the mental into mental arithmetic.

[-] randomwords@midwest.social 1 points 1 year ago

Again people making me defend imperial, I think metric is better.

I see this argument all the time, converting between these units is hard cause the numbers are weird. You have to stop thinking about imperial as a system, it's not. No one should convert miles to feet, they are not intended to measure on the same scale.

None of the conversions are easy because imperial is just a random collection of units that were being used to measure different things.

[-] yA3xAKQMbq@lemm.ee 0 points 1 year ago

Yeah, no one should be able to make a quick sanity check for things that span multiple powers.

  • "Hey Bob, we have 5000 of those 78 ft rails, that enough for the 100 mile railroad?"

  • "What do I look like, a fucking calculator?"

vs

  • "Hallo Heinz, how mäny hecto-liter do ve kneed für 1000 0.5l bottles of Bier?"

  • "20, boss."

The amount of people going completely out of their way to die on their little cubic ft hill actually defending they're incapable of easily and consistenly calculating units is just utterly ridiculous. "Nobody should be doing this!!!1!"

No, wait, the people in here telling people that "dozenal" is superior, but not realizing they're not using a "dozenal" system at all, they're just counting to twelve in decimal. Those are also making me question whether humans actually went to the moon...

[-] randomwords@midwest.social 1 points 1 year ago

Keep putting those words in my mouth. I'm not dieing on any hill, just trying to provide some context about why imperial is so weird. I still think metric is better.

You seem really upset about something that really doesn't matter that much, are you okay?

The versions of imperial measurements the US uses are even defined in terms of metric units, so they're less a completely separate measurement system these days and more just a weird facade on top of metric, even.

When I find a wood working video on YouTube from the states it blows my mind how anyone can not just adopt metric “This is 5” 4/57 and we need to cut it to 5” 5/45 and a half” bzzzzzzz.

[-] PRUSSIA_x86@lemmy.world 0 points 1 year ago

I may be biased, but I think it kinda makes sense. All the fractions are really just powers of two:
One half
One quarter
One eighth
One sixteenth
One thirtysecond
etc.

[-] dancing_umbra@lemm.ee 1 points 1 year ago

There are some places that do use a base 12 number system.

Again, I wasn't defending it, just explaining it.

[-] Gleddified@lemmy.ca 1 points 1 year ago

Base 12 is way more logical than base 10, I bet aliens would think we're stupid for counting in base 10 just because we have 10 fingers, my opinion on this is infallible fight me

[-] bastian_5@sh.itjust.works 1 points 1 year ago

It's not entirely without logic. Base 12 is actually better that base 10 for a start, as it allows for a lot more fractions that have clean representations, so 12 inches in a foot is fine. The next thing is that people seem to think we have all of these strange units with strange conversions, when in reality we have 3 units for short distances, and then a seperate unit for long distances. 12 inches in a foot, 3 feet in a yard, and then nobody cares how long a mile is in terms of feet or yards. Once you realize that the mile is not even really part of the same measuring system as inches, feet and yards, the weird conversion makes sense. We exclusively use miles to talk about long distances above 0.1 miles, and then yards are used below 500 yards (which has an overlap of 324 yards). And then for the logic, it is entirely based on actual human scale shit. A foot is called a foot because it is roughly the size of your foot. A yard is approximately how long one stride is. Saying something is 100 yards away means it is approximate 100 steps away. Obviously there will be a bit of variance for how accurate that will be for any given person (and children will have to base it off of an adult obviously), but because it is based more on human things it is more useful for measuring human scale things. It was designed to not use decimals or large numbers because humans don't comprehend those very well.

[-] DeriHunter@lemmy.world 3 points 1 year ago

Yes very logical, much intuitive

[-] surely_not_a_bot@lemmy.world 1 points 1 year ago

In this thread: people bending over backwards to defend their insane, non-logical unit of measurement

[-] themeatbridge@lemmy.world 0 points 1 year ago* (last edited 1 year ago)

Logical, mathematically convenient, but not practically convenient. Without a measuring tool, there's no good way to estimate anything besides a centimeter.

Every imperial unit of measure can be estimated whilst naked (but preferably clothed).

An inch is your distal thumb phalanx. A foot is your foot. A mile is, or was at one point, roughly 1,000 paces.

The weather can be estimated by going outside. Is it too hot? It's in the upper third of the 100 degree scale. Too cold? Lower third, might snow. Cool enough to fully dress, but not too cold, right in the middle.

A healthy, big person is about 200 lbs. A very small person is about 100 lbs.

Converting between these units is useful in science, which is why science uses metric. But you could live your entire life on earth and never need to know how many distal phanages are in 1,000 paces. It literally never comes up. Who cares?

It's why units are divided into fractions, rather than into a decimal system.

By the way, the only reason we use a base 10 numbering system in the first place is because we have ten fingers and it was easier for early mathematicians to count. But I digress.

If you're dividing a length of rope, and all you have is the rope, it's simple to divide it in half, and then half again, and then again in half. You could even divide into thirds, if you were feeling frisky. You just fold it over itself until the lengths are even. There are two friendly numbers that are difficult to do that with, though. Can you guess what they are? If you guessed 5 and 10, you nailed it, good job.

Same with piles of grain or hunks of beef or chunks of precious metals.

But what about units of volume, you ask? I don't have a part of my body that holds roughly 8 oz of fluid to pour out. No, for that you'll need a cup. Just a cup. Not a graduated cup with a bunch of little lines down the side. 1 cup. Or half a cup, or a third, or maybe a quarter cup. Again, easily divisible for easy measuring without any special tools.

But a gallon, you protest. A gallon is 16 cups! What the fuck is 16 cups good for? Why not 10 or 100, or create a decigallon for simple math? Because 16 can be divided in half 4 times. Measuring out portions of the whole is as simple as pouring out equal portions into similarly sized containers. Divisible numbers are easier to use without graduated equipment.

And that's why time is measured in 24 hours, each hour is 60 minutes, each minute is 60 seconds. There's a ton of history there, and we'll ignore for this discussion the inaccuracy of measuring a day or a year. If the metric system is entirely superior, why don't you demand we all switch to metric time? A year will still be roughly 365 days (again, setting aside the inaccuracy) but we could divide the day into 10 equal metric hours, or mours, and those mours into 100 metric minutes, or metrinutes, and then those metrinutes into 100 metric seconds, or meconds. 1 mecond would be 0.864 seconds, and a metrinute would be 1.44 minutes, which to most people would be an imperceptible difference in time. Hey, how many seconds is 1.44 minutes? You don't know without a calculator because we don't use metric for time, and it probably never bothered you once before now. What an insane, non-logical unit of measure time is.

Yes, metric let's us convert millimeters to kilometers, or helps us determine how many calories it take increase 1 cubic centimeter of water by 10 degrees kelvin. It helps with those things because the units are arbitrarily defined to make the math easier, not to make the measurement easier. But that's it, there's no additional sanity, no additional logic. It's easier to convert between units via math, because it was designed to be easier to convert between units via math. There are no additional benefits to the metric system.

[-] Atomic@sh.itjust.works 0 points 1 year ago

A foot is a foot. Fantastic. Glad to know everyone has the same sized feet.

And the same length on their legs so we all pace the same distance.

I would say good troll, but it just seems too long to be ironic.

how about we all agree that the best system is american units with metric prefixes. After all it is obvious that it takes an hours to drive 318 kilofeet

[-] quinkin@lemmy.world 1 points 1 year ago

Ah nice, this should be a constructive dialogue between open minded and empathetic individuals.

grabs popcorn

I'll just leave this here: https://youtu.be/iJymKowx8cY

TLDW: metric is better because all the different kinds of units were designed to work together.

Where as imperial units developed organically, within specific trades/use cases. They're not all supposed to work together.

I use imperial because that's what I was raised with, but I recognize metric is better in many ways. My only gripe with metric is the gap in units between Centimeters and Meters. A foot is convenient size for most things.

[-] DrQuint@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

A truly logic system would be entirely designed around a base-12 number system. But we were born with an imperfect set of 10 fingers and that doomed us.

Those aliens have 6 fingers. It's an absolutely ironic twist that their discussion on measuring systems is super illogical for them, and yet logical is the verbiage they use.

[-] cantsurf@lemm.ee 0 points 1 year ago

Care to elaborate on how base 12 would be better than base 10 in this case?

[-] ShinyShelder@lemmy.world 1 points 1 year ago

Basically it's because 12 is more divisible than 10. Factors of 10 are 1,2,5 and 10. 12 has 1,2,3,4,6 and 12. This gives more flexibility when discussing numbers. Our time is technically using base 12, which is why we can say quarter past 4 and it means a traditional whole number. That's the argument I've heard anyway

[-] 98jf98@lemmy.world 0 points 1 year ago

When my American friends insist that feet and inches is just easier for them, I just nod in agreement and give them measurements using rods, chains and furlongs as well. If you're going to go Imperial, you have to know 'em all. An acre is a chain by a furlong, totally logical as that would be 4x40 rods which is of course 43560 square feet. I guess it makes complete sense when your world is only a few furlongs across.
