Made yes, and hanging someone for making such statements would be out of 
bounds, but criticism is certainly justified. IM(H?)O criticizing such 
criticism is [self-censorship kicks in].

no, definitely by its mass. weighting instruments used are calibrated to 
read the mass *at the place they were calibrated*, so nothing wrong with 
asking for mass. It even prepares for interstellar trade.

Glimpse from my 6-y old son trying to understand our sometimes confusing 
world: kilo is a synonym for 1000, as in km. but it is also a synonym 
for 1000g. He is (rightly?) blaming the world for being illogical. He is 
in for an interesting life.
