A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

As someone not born to the metric system but who’s tried to lean into it, this is something I’ve always found a little difficult. “A thousandth of a meter” isn’t a useful concept to me. I don’t think we are good at conceiving of things in their thousands, with good proportionality. I would rather just have a singular name like “squajibbles” for milimeters and memorize an intuitive sense of what that is. I realize I can do that with the word “milimeters” too but my brain sometimes gets stuck on unpacking the math. I was reading Dune last night and the expression “millions of decaliters” really stopped me in my tracks. I felt like I had to start with one liter, a sodastream bottle, and multiply it up. I’d rather have some concept like “fuckajiter” which means an Olympic swimming pool and work with that.
Not really being critical here. Metric is better. But intuitiveness is one of the qualities of a measurements system that makes it more or less appealing and I’ve always found imperial has a slight edge there that makes it harder to just drop as a complete loser of a system.
EDIT: yes, internet, I know the only legal thing to say about metric / imperial is that metric is the only system and imperial is for American asshole cavemen. Oh well. Fuck me for offering thoughts from someone trying to move to metric. I should hide my shame.
This is, in fact, exactly what metric users do in their daily lives... We don't do math in our heads every time we measure something. We know from experience how large all the units are and pick the one that's appropriate for a given situation, just like you do.
When you measure something using inches, you don't then say "it's this many 1/36ths of a yard" unless you specifically need to convert it into yards for some reason.
Similarly, when we measure something using millimeters, we don't say "it's this many 1/1000ths of a meter". It's just a millimeter. Don't get hung up on the prefix, just ignore it and treat it as a unit of a particular size.
I figured that’s what people born to metric do. It’s different when you’re learning it as an outsider, as an adult consciously absorbing the system.
As a Canadian with a living memory of when we made the switch here, I feel your pain. Though to be fair, I was a child at the time and so probably had an easier time of it? But in some ways, I'm still transitioning to this day!
Take temperature, for example. When Canada went metric, all the weather reports switched to Celsius but our indoor thermometers and thermostat were still in Fahrenheit. So I wound up in a situation in which outdoor extreme temperatures became more relatable in C, while typical indoor temperature ranges sounded better in F. I particularly liked winter temperatures in C. It was so intuitive that < 0 means snow and > 0 means rain.
Today, I am more comfortable with C for indoors as well, but not for cooking. I guess that's because a lot of recipes still say set the oven to 350 or check the meat on the grill is at least 160?
The point isn't to have an intuitive sense of what a millimeter is just by knowing what a meter is. You have to learn both units individually to have intuition about them. The point is to know that a measurement of 500mm is 0.5m without having to do any math in your head beyond moving a decimal point.
Yes but when you don’t have that intuitive sense through extensive use or being born to it, the math gets in the way as you’re trying to form it.
I'm an American in my mid-forties and that has not been my experience at all.
I dont see a Millimeter as a thousandth of a meter, I see it as a tenth of a centimeter
Scale is what matters. when I measure something in meters I dont care about the exact millimeters
Coming from the UK generation that grew up during the decimalisation process, and therefore being equally comfortable with both systems, imperial measures are far less intuitive than metric. Don’t mistake simply being being used to something as it being intuitive.
We use a base 10 numeric system because that’s how many fingers & thumbs we have. Having a system of weights and measures based on that decimal system, is far more intuitive than a system that scales up through orders of distance using different scaling factors at ever order, is so unintuitive as to be absurd.
Right but if basing things on our hands makes them intuitive, it’s hard to beat “hands” and “feet” for human scale relatability.
As a craftsman, I live milimeters for precision. Very useful and easy to work with. I hate not having anything between centimeters and meters though. I know decimeters exist but nothing’s ever listed that way and so it isn’t something I’ve developed any intuitive sense of.
When I sent some measurements to my uncle to make a bed, I sent it in 200cm x 160cm. Not 2m or 20 dm. You know those exchanges because it's obvious but since people are used to cm for height, it's useful to compare stuff with yourself and that's why cm is the most used measurement for craft.
If whatever you are building fits in a hand, measurements will probably come in mm, because idk why but people enjoy 3 digit measurements.
Me, my wife, my child all have differently sized feet and hands.
Tbh, as an european I kinda absorbed a lot of imperial by just living on the anglophone internet, and honestly have nothing good to say about it.
I can intuitively guesstimate what a mile, yard, foot and inch are in metric, and I do, because it's useful in my particular corner of the Internet, not because it's a good system.
I have no idea what a gallon, stone, lbs or oz are. Volume of itself is kinda unintuitive, same with weight. Can't be bothered.
Intuitiveness comes with usage. When I think of a kilometre, I don't think of a lot of metres, I just think of it as a single unit. A centimetre doesn't send me dividing metres, I just think of a length about the width of a fingernail.
if you actually use the metric system, millimeter would become that "singular name" you memorize for a certain length. but you could also tell from the name alone what's it about roughly, squajibbles on the other hand...
You just named the main advantage of the metric system as unintuitive and the opposite (squajibbles, fuckajiter, feet, toes, elbows) as the main advantage of the imperial system. Yet, you say that metric is better. I don't understand. Why do you find metric better then?
I understand that intuitiveness is subjective and that how a person is raised or lectured alters the view on what is intuitive. From a logical perspective, however, I find the metric system much more intuitive as the names of the metrics denote exactly what we are dealing with (except for the case of tonnes). Yes, maybe the wording is confusing. But from the word itself you can infer what is meant, given you know what milli, giga, mega, nano, pico, etc mean. Its just times or divided by 1000. What is feet in miles or nautical miles? Gotta look that up!
Well metric is obviously better for conversions which helps a great deal. I think my intuition problem either goes away with extensive use or being born to it.
I do really like the “foot” as a highly human-relatable unit. At 4 feet tall, a man is aberrantly small or a dwarf. At 5 feet tall, a man is normal but short. At six feet high, a man is tall. At 7 feet tall, he is aberrantly big. It’s a highly usable human scale thing and there isn’t a great analogue in metric. Maybe you get used to decimeters (wait… decameters?) too but they are less commonly used. Giving someone’s height in centimeters has never gotten familiar for me. And the deca/deci thing I think undermines your intuitive point a little. These are easily confused.
I think millimeters and milliliters are great for precision. Imperial sucks below 1 inch or 1 ounce. All fraction bullshit.
So each system has its pluses on intuition. But metric has the conversions advantage and the precision advantage so that’s what wins for me.
Wait isn't imperial the one with asinine fractions?
Like wtf is a 64th of an inch? Or a thousandth (is that how you spell that?)
