A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

The army uses metric almost exclusively. It’s where I learned it.
Yep. One "klick" is one km.
I think the main problem US people have with metric is their aversion to anything that has more than two syllables.
Far worse: It’s laziness.
I was teaching a friend how to make ravioli (yes, really) from the class I took while over in Italy. I bring my scale to measure the dough and the first thing she does is use the scale to get the right measurements and then, scrapes the contents into an imperial measuring cup. Worse, she was totally pissed when the semolina was not a perfect match to the 00 flour (mass and all that).
She is a tried and true American. She just wants to whip out her 1 cup without measuring weight and can’t fathom why the dough just “wasn’t like I taught her”.
By the way, the super secret Italian recipe is this: Ingredients per 2 people (spaghetti or tagliatelle) 100 grams total of: 50% white superfine flour 50% semolina Add 1 egg per 100 grams of flour
For ravioli, you want more superfine (00) flour so the pasta sticks together better. So like above, 100 grams total of: 60% superfine flour 40% semolina
Add 1 egg per 100 grams of flour.
But I want it to be one cup of egg!
Medium or large eggs, (the most common size) is about 5 eggs per cup, 4 per cup of extra large. - YMMV slightly depending the exact eggs your have.
Of course there's a cup measurement for eggs.
What was I thinking.
To be honest, ain't nobody using that measurement unless you are using commercial canned shelled eggs for speed. And even then you are probably just going to open the can and dump the whole thing. But it does show that the system is complete.
Rare indeed would be the home cooks/bakers that used that.
Go for it
What most people miss about weight vs volumetric measurement when cooking is that it's all about ratios. And if you had been paying attention in math class, you would know that ratios are unit less. Which means as long as you keep the proper ratio between the ingredients, it matters not one whit on how you measure them. You can weight, you can use cups or spoons or handfuls and pinches to achieve the correct ratio. You even demonstrate this by stating that the ratio of flour to semolina is 1:1 or 3:2 depending on the end use. And one extra large egg, (about 55 grams or 2oz), should make for a decent conversion.
But before you change units of measure, you need to be sure that the changes still hold to with the tolerances of the recipe. Something most people can't do very well - much like your friend.
And never forget - the true masters of fresh pasta making at home are all those little old Italian Grandmothers. And they are probably just eyballing it all anyway.
The problem with converting a 1:1 ratio of ingredients measured by weight and a 1:1 ratio of ingredients measured by volume is density. Two different kinds of flour may pack differently and thus have different densities enough to effect the consistency of the dough. And with something like flour, a cup of sifted flour is less wheat and more air than a cup of scooped flour.
It's all about the ratio. The density does not matter as much as you seem to think. Plus there is a tolerance built in. Just think, you so carefully measure everything out with weight (did you get the weight exact?). Then you randomly toss a bunch of bench flour down when you kneed the dough. You have literally no clue as to how much weight of flour/semolina the dough picked up. So it really doesn't matter as much as you might think. Now your scale does make it easier for you. And that's fine, I have a kitchen scale and use it regularly myself. But I understand it doesn't matter as much as you seem to feel it does.
And again, those Italian Grandmothers are just eyeballin' everything anyway.
To be fair you sound like Data from TNG Season 1 if you say something like "Give them a centimeter, soon they have a meter."
Except in electronics. Everything is still .1 inch headers. We invented too many electronics and it’s stuck now.
It is also annoying that the electronics industry prefers the term “mil” for 1 thousands of an inch. Why not use “thou” like machinist use?
Not all of it though. Like JST plugs, barrel connectors, breadboard pin spacing, etc.
