[GreenKeys] The Metric System (was Independence Day

[WA5CAB at cs.com]

It was probably invented by French and/or Germans but as far as perfecting 
it, unh unh! Just take the ISO Metric threaded fastener system. Worst 
real-world threaded fastener system ever devised. Thread pitch is too fine. Hex 
nuts and hex cap screw heads are too small. Screw heads are too small. Screw 
slots are too narrow. The system is only usable in (a) a Clean Room or (b) a 
"total consumer" economy where when something stops working instead of 
fixing it, it goes to a land fill and a new one (that usually doesn't work as 
well as the old one) has to be bought.

Inconveniently sized basic units is another built-in bad feature. In many 
cases, you have to use a million of them or a millionth of one of them to get 
to the "real world".
