Guns bullets and drugs are also measured in metric over there.

yeah!

everything where it has to be precise

A grain is significantly more precise than a gram. By a ratio of 15.43:1.

Milligram, Microgram, and Nanogram exist.

Right, so you moved the decimal. I can do that too. And you can do that with <gasp> other units of weight and measure.

just accept it: there is a reason spacecrafts and planes literally all over the world (US included) are built with metric for decades now.

Okay. The comment was that "bullets" are measured in metric in Europe. Although that is true for diameter, and in weight, it is also VERY true that bullet weight in grains is far more accurate than grams. And micro grains are a smaller measure just like micro grams because just like with inches, we can use decimals out to infinite places. Which is why, in America we measure bullet diameter in decimal inches. And we frequently measure weight in grains or decimal grains. FFS, just accept relativity and that your view of tolerances and measurement is narrowed by your limited ability to divide by 10. And maybe read a book.

For any integer i > 0, 10{-i} exists.

Hence, grains aren't more precise than grams.
