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. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

but its more convenient to have smaller units depending on what you're measuring.

See, that’s what apparently many people don’t understand: with metric you don’t have „larger or smaller units“. You have one unit and you scale it to your needs. It’s not like we have „the meter“ and „the centimeter“ and have no clue what’s in between. There’s absolutely nothing more convenient about having multiple units for the same physical property.

I find the size of a foot to be convenient for measuring things in casual situations where accuracy and precision aren't priorities.

Again: There’s nothing more or less precise about metric or imperial. You have a mental image of a „foot“ the same way I have a mental image of a ruler or a sheet of paper, i.e. 30 cm.

I don’t really know what a litre is. I know what a beer bottle looks like, or a milk carton, the same way you know what a quart of milk looks like. Pour a quart on the floor and ask someone how much that is, they probably don’t know.

We don't literally measure it with our feet, that's just what its called.

Oh, I definitely had other people tell me imperial is „more human“ because a foot is the size of your foot and an inch is the size of the tip of your thumb.

That's the same thing, the units are just proportional.

I know, its just easier to say a foot than 30 centimeters. That's why I use it in casual conversation, and not in anything important.

That's not the part I'm saying is convenient.

They can both be used to measure things precisely, but metric is more convenient in those situations usually. If I need to accurately measure something, I would use metric because the advantages of imperial are probably not applicable. If I'm just estimating and it doesn't matter much, I'll probably use imperial because I won't have to do any conversions with that number, or anything else imperial struggles with.

Those people are wrong.

Sure, if you put it like that. But I do have the feeling many US people treat imperial units like completely different things and have absolutely no mental concept of a relation between them, especially between length and volume.

That’s just a completely arbitrary thing. It’s easier to answer „how tall are you“ with „one eighty“ instead of „five foot eleven“ 🤷‍♀️

It doesn’t seem to be an issue for „metric people“ at all, nobody is missing the foot in Europe.

Because if it were convenient we would have that, the same way we have a ton, or a pound (500 g), which are in common use. You have the decimeter (10 cm), but nobody uses it. There used to be a unit called „Elle“, which is 50 cm, and it’s just the name for the stick, nobody says „give me 3 Ellen of canvas“.

I would use metric because the advantages of imperial are probably not applicable.

I still fail to see those advantages.

Yes, because you’re used doing so, not because it’s more practical or convenient. Metric people do estimate things as well.

There is certainly no shortage of Americans that don't understand the metric system, or hate it for nonsensical reasons. I was once asked to measure a piece of wood and I said it in centimeters because it was exactly x cm long, and they said something to the effect of "not that commie shit". They seriously wanted to work with fractions of an inch instead of touching that evil foreign system.

Its arbitrary if its not something you care about. Also that's not a great example for height. Usually its just two syllables. 5' 4", 5' 5" etc. You only have to say foot if you are an exact number of feet tall. That way you don't tell anyone "I'm 6". Most people's height in cm will not be a multiple of ten, so it will be longer than 180's three syllables.

It doesn’t seem to be an issue for „metric people“ at all, nobody is missing the foot in Europe.

It's just an inconvenience, it's not worth learning imperial to save a little time. Especially when no one around you would understand what you're talking about.

I still fail to see those advantages.

The units are usually sized intuitively for everyday use. Just look at Fahrenheit vs Celsius. The only thing I use Fahrenheit for is the weather. 0 is too cold, 100 is too hot. That's subjective of course, but it seems more intuitive to me than Celsius. The boiling point of water doesn't matter to me when I'm deciding what clothes to wear for the weather. Celsius works fine but it makes less sense for that application in my opinion.

Yes, because you’re used doing so, not because it’s more practical or convenient.

Or, Europeans only use metric for those things because they don't know imperial. I'm not saying that's a bad thing either, if you don't know imperial then its not worth learning. The advantages are small enough that its not worth the effort, but that doesn't mean they don't exist.
