Very useful rules, I see… impossible to bypass :-)

Interesting, you just replaced losers and clueless in the gervaise principle

Km is 10³m cm is 10^-2m so the difference is 10⁵ i.e. 100000 (one with 5 zeroes)

Or more intuitively one centi-meter is a 1/100 of a meter and Kilo-Meter is 1000 meter therefore 100*1000 100000

It is quite intuitive, once you start using it

What’s weird is why we don’t use Megameters and megagrams (i.e. one metric ton)

Funghi

Well math might be, physics for sure isn’t

not yet

The same can be said for banknotes, they are quite useless as paper, they are mostly valuable because people see them as valuable and perceptions can change

1446 m/s is more than mach 3… I don’t think that plane can do that

Not really, the chances to find a winning ticket of a lottery walking on the street is almost comparable
