    Having read a good portion of the comments in this thread and the anti-american sentiment attached, I am convinced that the only reason the US isn’t wholly metric at this point is out of spite.

    I know the actual reason is that it would cost too damn much to convert all the infrastructure we’ve built in imperial, but now I just want the USA to keep kicking everyone in the balls at the Olympics, in the military, and with global corporate supremacy just to own it to the world that they’re better than all of you AND they use imperial.

  • When I learned the consistency (synergy?) between metric measures, I thought that was so amazing.

    In the olden days sciencey types and engineers kept fact books listing such relations. They had a specific name that escapes me.

    Before handheld calculators, they also kept books of pre-calculated mathematical operations, so they were used to having numbers books around.

    Wait, no, this isn’t really correct.

    Metric is the first part, but it is also the second part. The entire point of imperial units is that they ARE humanistically intuitive measurements.

    Science = metric, relatable = imperial.

    Imperial doesn’t care about how many units of energy it takes to boil x quantity of water at y elevation pressure etc, and that’s the whole point, it’s about how many approximately hands tall is this horse. You look at your hand, look at the horse, and go “about 15”. If you want to know exactly how tall a horse is, relative to human height, you use feet and inches. Everything has its own, weird systems of measurement that got made up over time, organically relative to other human approximation.

    Metric if you want standardization and exactness and conversion, but imperial works fine as long as you know of the units, because we make up our own units that make sense. Like, the south park kouric unit is an example. It doesn’t matter what the unit is derived from, you just need to know is it ten or eleven or twelve, because the units are relative to us, not how many units of energy it takes to heat a cubic meter of water to boiling at exactly one atmosphere, because that’s insane. Cool, and converts well and is universal, but the numbers don’t really mean anything.

    I really think context matters, and if you work well with metric for everything - fantastic. If you work well with imperial - great. They’re just different systems for different purposes for different situations.

      We have also units in metric, except it’s always the same ones. Horse is around 2m and a small banana is 15cm, a human foot in around 30cm.

      You can measure the parts of your body to get to the same point reference pretty fast and it’s very relatable when you live in a non-imperial country.

      Metric is very relatable if you just, use it, just like imperial.

      The only difference is metric is also easy to scale up or down, imperial is pure “fee-fees”

      Your implication that metric is not humanistically intuitive is just bonkers when you consider 99.125% of the developed world just uses metric for their every day, always, with no issue.

      Germans, Koreans, and Indians aren’t suddenly going “oh no! I can’t measure these shoes and these plates! I only have SCIENCE numbers, not BaldEagleBananaBurgerFreedom™ numbers!”

        I expanded my comment, but, basically, you can get used to any system. Humans are incredibly adaptable.

        But for the same reason we’re bad at conceptualizing how rich a trillionaire really is, metric may not be better than imperial. Or, maybe imperial is the reason we’re bad at conceptualizing! I haven’t thought about that before! But it’s an interesting idea!

        Like, I’m at a shop right now, and outside the window are some scooters.

        How many scooters?

        I think in units of scooters, not pieces of metal in scooter shape that add up to a volume of mass and energy. Because that’s not what I’m thinking about right now, I just see six scooters, and you instantly know that there are six scooters.

            This is true, but that’s because everybody has accepted the unit of scooter as the accepted unit count for scooters…

            Okay that’s a bad example, because just counting things is the way to count things. But also, maybe that’s the point - maybe, counting things is just super simple, and why direct or single-level abstract measurements is the difference: metric = relating everything to a single point, and imperial = just counting. Yeah? Maybe?

              I’m not really following. What, are we counting feet, then? Mine?

              Feet are just really entrenched in the way Americans think about lengths. It may not sound like it’s abstract, but it is. If I said “yeah, it’s about sixteen hands long”, people would have to parse wtf I’m talking about, but then have to grapple with how long a “hand” is exactly and what 16 of them means.

                The foot is no less arbitrary than the meter. If you are just unfamiliar with the unit and confused by the fact it’s named after something often close in size to it that’s fine, but keep in mind for a while a meter was defined as the length of a specific metal rod, same as the foot and yard.

                  I was with you until you said the foot is no less arbitrary than the meter. The foot is just a useful size and changed depending on whenever the king decided. The meter was defined by the French using Earth. To say they’re both equally arbitrary is untrue.

                  Imperial units are nice to work in when accuracy is more important than precision. Want a third of a foot, that’s four inches exactly. A third of a meter is 33.333 cm repeated. It really depends on the situation which is more useful, but metric is more often than not the useful choice.

                  Yeah, they’re both arbitrary. You agree with me.

                  The “things” being counted in either respect are abstract and are only “known” if they are familiar.

    True except for calorie. Metric typically uses Joules, which is good because it’s just the product of force (N) and distance units (m), instead of requiring a conversion factor.

    Metric is great for scientists in a lab with equipment to measure things.

    Imperial was created during a time when peasants in the middle of nowhere needed to measure something “close enough” to trade with others, even without tools or measuring equipment, which was only owned by scribes and other members of the nobility.

    This is why all imperial length measurements relate to parts of the body and why all volume and weight measurements relate to containers that were commonly used to store the thing you’re measuring (a bushel of grain, for example).

    Also, a foot can be divided equally into 2, 3, 4, or 6 equally-sized pieces without resorting to estimation or irrational numbers; a meter cannot.

    The US agreed to switch to the metric system centuries ago, but the ship carrying the official units sank on the way over.

      Metric is just as great for everyday life as imperial units.

      While I agree in principle, I also enjoy the chaos that imperial system causes when you try adding up 1 1/8 inches + 5 27/32 inches + 7 3/16 inches instead of just using decimal numbers.

        This is what the metricians say to feel better about themselves, but they never mean it.

        “Oh yes, I’ll have a 236.588 milliliters of tea, thank you for offering”

        “The kids are out playing in the back 0.914 meters”

        “Doctor, I think I broke my left 30.48 centimeters”

        Do you see how silly you would sound if you didn’t use imperial?

        1 1/8 inches + 5 27/32 inches + 7 3/16 inches

        1/8 = 4/32
        3/16 = 6/32
        4 + 6 + 27 = 37
        37/32 = 1 5/32
        1 + 5 + 7 + 1 = 14
        Total: 14 5/32
        

        I wouldn’t call it chaos, it’s a straightforward algorithm:

        1. Identify the largest denominator
        2. Multiply each other fraction by [largest denominator divided by current fraction’s denominator] (e.g. 32/8 = 4, so 1/8 * 4/4 = 4/32)
        3. Determine the sum of every numerator
        4. Divide and simplify the number if necessary
        5. Determine the sum of the integers, including any integers added in the previous step

        This works for every measurement because the denominator is always a power of 2.

        With that said I absolutely prefer metric.

          In practice you would just use decimal inches. Doesn’t really make it better but you can machine something without ever seeing a fraction if you want to since everything will be in thousandths of an inch.

        Having done my share of automotive and carpentry work, I’ve never in my life had to go down to 64ths. 32nds is the smallest fraction I’ve ever had to use and the amount of times I’ve had to get that small could probably be counted on one hand.

      Metric allows you to convert between length volume and mass in your head. Someone smarter than me could probably take a reasonable estimate of how long a kettle will take to boil just by knowing it’s wattage and estimating its volume.

      You’re right that “pounds” may have e been a practical measurement back when people didn’t have calibrated and everyone’s hand weighed a pound. However, that advantage ceased once everyone standardised those measurements.

      A metre is equally divisible by 50, 25, 20, 10, 5, and 2. There arr numerous advantages to a base 10 system.

      Every country used a system based off body parts or similarly easy-to-measure parts. When the metric system was invented, most of them switched because it was the logic thing to do. Some just decided that the dumb system was better who knows why.

      Spain adopted the metric system in 1852 and by the time, they weren’t the most advanced country.

      “In fact, imperial is so great because duodecimal invites so much divisibility! What’s that? You’re saying it goes 12 –> 3 –> 1760 for length, 16 –> 2000 for units of mass, that units of volume are a bastardized base-2 system where there isn’t even a consistent multiple between units, and that pounds and short tons aren’t cleanly divisible by 3? And that not a single unit of volume is divisible by 3 unless you bring it down to the level of teaspoons?”

      “‘Why not just switch to a fully duodecimal system if divisibility is so important to you’, you ask? Well fuck you, a foot is about as long specifically as my forearm, and there’s no way my poor, emaciated monkey brain would ever have found something similar to latch onto with SI units. Those people living in most of the rest of the world probably just carry meter sticks around up their asses. ‘How many square inches is a 30 x 30-foot room?’, you ask? Well fuck you again.”

      In imperial, pounds can be either a mass or a force, or context dependent, or a slug might be the unit for mass derived from the pound force. The foot pound force is a unit for energy.

      Honestly the system shouldn’t exist.

      The last bit of rationalizing is hilarious. It’s like you don’t even understand numbers or math, well what am I saying, you’re an American

      We can figure out what 70% of a meter is.

      Good luck with your peasant system

        Its crazy how many people upvoted this comment. Didn’t realize there was so much anti-american sentiment on this platform. I get the government is shit, but insulting the general population just kinda makes you out as an ass.

      What do you mean you can not divide a meter without estimations or irrational numbers? Do you mean fractions or decimal? 1m/3=3.33… dm ( repeating, which means it is a rational fraction)

        Anyone who thinks you can divide one number by another and get an irrational number… doesn’t know what irrational means.

            irrational numbers are numbers which are not a ratio of integers

            complex numbers, often called “imaginary” numbers, are ones with components of unit i =√-1

              complex numbers, often called “imaginary” numbers,

              Aside: mostly, but complex numbers are an addition of both a real number and an imaginary number: a + bi. It just happens that a can be 0, making it a strictly irrational number when b ≠ 0.

              Thus, the imaginary numbers are a strict subset of the complex numbers.

      Also, US Customary units share many of the same terms as Imperial, but the actual quantities differ.

        Even more fun is that US customary units are explicitly defined by their metric equivalents. So the US is using metric whether they like it or not, they just slap pointless conversion factors on top.

          And it’s been this way since 1893. The US customary system has been sneaky metric that whole time.

    I can’t remember what book this was from, it was a medical thriller about an ex-con in witness protection IIRC. I think it also includes him sending an intern to check on “the LD50 of falling out of a window”

        Okay, then, how much energy does it take to boil 1mL of water from room temperature? (Note that I said “boil,” not raise it to 100°C.)

          We will assume that room temperature is 20° C. The heat of enthalpy is 2257 kJ/kg, or 2.257 kJ/g. As stated previously, the amount of energy to raise water 1 degree is 1 cal, which also equals 4.184 J. So,

          (100-20) × 4.184 + 2257 =

          80 × 4.184 + 2257 =

          334.72 + 2257 =

          2592 J rounded to the nearest whole number. This will leave you with a dry pot.

          Now show me the process using Fahrenheit, fluid ounces, and foot-pounds.

            It’s about 1 BTU per fluid ounce per degree Fahrenheit, so:

            128 fl oz × (212 - 68)°F × 1BTU/fl oz•°F = 18,432 BTU

            Add in the enthalpy of vaporization:

            7.5 BTU/fl oz × 128 fl oz = 960 BTU

            So, about 19,392 BTU.

            I’m cooking pasta for dinner, and I didn’t do any calculations. I just put the water in the pot on the stove, and waited for it to boil. Which was kind of the point of my question. Metric is all neat and elegant, but that’s irrelevant in daily life, because if I did have to calculate the energy requirement, I’d have to look up the enthalpy value, because it’s not memorable, as well as figuring in the actual atmospheric pressure to determine the actual boiling temperature. It makes all the sense in the world to use SI where it matters (e.g. science experiments), but customary units persist because in so much of daily life, it doesn’t matter.

              So your argument is we don’t need this in everyday life. Sure, that’s sort of true, but I guarantee this was necessary in making a stove that would work in your area. But also true is that if it doesn’t matter that much in day-to-day life, then the only reason to keep such a clunky system is familiarity.

              Also, 1 BTU is the amount of energy to raise the temperature of 1 pound of water 1 degree F. So your calculations are already off by a factor of 128. Given the world doesn’t need you to know the numbers for water to boil, that doesn’t affect much, but perhaps the vastly higher number for heating the water versus the amount of energy to get the water to vaporize should have clued you in that something was weird. It’s easy to tell in metric because most of the dimensional conversion values are 1 or factors of 10.

              There are people who like to dismiss the value of knowledge because it isn’t important in their daily lives. This is only true if you live in a hut where the only sources of force are human, animal, or fire, or there is someone unseen that you rely on who has used those tools extensively to provide you a life where knowing that isnt necessary. Raising the bar with ridiculous conversion calculations every step of the way makes understanding these concepts more difficult for the layperson and makes the field harder to enter.
