A question... Why do humans (or at least engineers) work so well in 1,000? I mean. I use milli/micro/nano/pico as an electrical engineer every day, and it's so intuitive to me. But why three orders of magnitude? Why not two orders, or five?
The way I remember Earth's approximate mass is the fact it's 10 times Avogadro's number in kg. My physics teacher always had a great way of drilling in these tidbits.

“The SI has been adopted as the official system of weights and measures by all nations in the world except for Myanmar, Liberia, and the United States.”

Earlier quoted context omitted.
> However metric prefixes need to be shortened to just their first letter—and B and H were already taken, ruling out bronto and hella.
Cyrillic small be (б) and Greek small chi (χ) could have been used instead.
