    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.

      What? Of course you ca split a METER into smaller pieces.

      500, 330, 250 and 115mm

      Easy as a pie.

      And no one is its right mind is actually using thirds. There is no way you can actually use thirds in anything but as an approximation

      That’s why duodecimal is superior to decimal.

      Instead of converting to metric, we should convert our entire numerical system to be base 12.

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

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

      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.

      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.

      Edited for clarity

        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.

              most electronics breadboards and the pins from (non-tiny) microchips / ICs are spaced at 2.54mm apart, which i eventually realised is a tenth 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.

          In US machine shops if they’re getting down to that level of measurement, they’ll switch over to milli-inches.

        If someone were adding those figures they would switch to decimal. I built furniture for 2 years, 64ths are almost never used over thousands of an inch. If you need to be finer than 32nds you use thou. And that pretty much only for wood. Machine shop I worked in used thou exclusively.

        But after multiplying, 8 + 54 + 3 over 64 is just clean fun, you end up with 14 1/64 inches and wanna die because you accidentally cut the material at 14 inches and now your whole day is ruined.

      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.

      “Decimalized currency is great for all those labcoats, but for us regular ol’ normal folk, it’s much easier to use real, easily divisible livres, which can be divided into 20 sous and subsequently into 12 deniers.”

      “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.”

      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.

              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.

      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.
