Chinesium runs 90% of all the smartphones in the world. Your tshirt is made of chinesium. You cars parts are chinesium. All of your electronics are chinesium.

If you're fine with using Chinesium whats the issue?

There must be or must have previously existed mechanisms which favored the production of matter over antimatter, quite simply. Alternatively, there’s other Hubble volumes which are antimatter dominated, they’re just not visible to us. Physics is just Lovecraftian terror

All units in metric have Non-physical definitions
a kilo is defined using the planck constant
a meter the amount light moves in a vacuum divided by 299792458
and a second is:
>The second is defined as being equal to the time duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the fundamental unperturbed ground-state of the caesium-133 atom.[1][2]
Also imperial is officially defined using the metric system

Imperial units have no advantages over metric, almost every country in the world ditched them long ago. Americans still use them because they're unable to admit they were wrong, so they'll keep defending them against any logic and reason. And that's a fact.

I buy American made clothes and drive an F-150, the most American vehicle by proportion. I will be buying a Librem 5 "made in the USA edition" phone when my current phone dies. I have several pieces of American made technology including old Unix workstations and a serial terminal. I was not even born or just a kid when the offshoring happened and vehemently disagree with it.

Fuck China.

Britbongs decided to do so, because in the long term not having to convert everything when doing some international business will pay off. The longer you wait, the more money you waste, and the more it will cost when you finally decide to switch.

More or less this. Metric is used without issue in academic and commercial applications that actually benefit from it, but there’s zero value in switching for day to day life.

Thats not how 50 centers post. Commie posters are the retarded blind nationalist.
I'm simply black pilling you of the reality of how "chinesium" has infiltrated your entire being. I'm reminding you of how stagnant western civilization has become. Its by design and not an accident. Its because your parents pushed their moral decisions to your kids. Its because you're living in denial of the reality that your parents created for you.

This is actually fun to think about. There might be whole realms of cuisine opened up by microgravity, not to mention solar ovens and possibly vacuum treatment. Someone should sponsor a research chef to fly into orbit.

Rear flaps are ~5-10 ton each. Or total of 10-20 ton for both rear flaps.

-30% in dimension probably yields atleast 30-40% weight savings. So - 35% would net give them extra 2.5 ton - 7 ton savings. However heatshields might eat that up.

the flaps are more surface area to add heat shielding to, not less, so factoring in heat shields only improves savings

I've heard that the main reason for the longevity of "imperial" (read: US customary) units in the US is actually because the US federal government formally standardized the US customary system for the whole country way back in the early 19th century, when the metric system was still in its infancy and most of Europe was, at least informally, still using a whole mess of different traditional systems of measurement that varied greatly from region to region. The adoption of the metric system by European nations later in the 19th century was intended to do away with this confusing mix of different systems, which is a problem the US didn't have in the first place. In the present day, close to 200 years of social inertia would probably make switching to an entirely different system for the entire country a slow and tedious process.

Consumer electronics are indeed still mostly sourced from China (although I believe some SEA countries are starting to make inroads in that manufacturing sector), but these days the textile industry appears to have mostly relocated labor operations to even poorer (per capita) countries. The shirt I'm wearing right now was made in Nicaragua, and countries like Bangladesh, Sri Lanka, Vietnam, Indonesia, Jordan, Ecuador and various other "3rd world" countries are commonly seen on clothing tags nowadays.
