I sometimes use millitonne (mt) instead of kilogram to keep people on their toes. I’ve learned that some people doesn’t like to have their weight measured in any kind of tonne.
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.
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!
I’ve often wondered why the kilogram was not called the gram when the former is commonly cited as the official unit of mass? I guess it doesn’t really matter much since it’s easy to convert between units. That’s sort of the point of metric, but still…
Apparently it was going to be, but they chose the kilogram instead.
Fair enough. But it’s interesting right? Like the litre lines up with the kilogram (for fluid measures) but they don’t call it a kilolitre for consistency’s sake?
This is one of two “warts” that I know of in SI. They wanted a coherent set of units, coherent meaning that no nuisance constants are required to convert between dimensions in the set. The system at the time was gram-centimeter-second. To expand things to all dimensions I suppose it was simpler to use the larger units, like J = kg m^2 / s^2 rather than trying to make a new unit for energy, etc. You’d think they’d have just come up with a new name for mass units and defined it as 1 kg, something like 1 prot = 1 kg, then all of the coherent units would be ones without prefixes. Someone must have really being going to bat for the word “gram” though, because now we have this pretty stupid rule that the coherent units are all of the ones without prefixes, except mass, which has the coherent unit of kg. And then also, prefixes are used to scale the coherent units by appending the appropriate letter to the coherent unit symbol, except for mass, for which g is treated as the coherent unit, even though it’s not.
It’s not the worst thing, but it’s pretty stupid to explain.
until you realize, that “second” is also not the base unit. it’s not at obvious because it isn’t metric, but second is just the second subdivision of an hour (the first being the minute)
