Why is a Japanese-Engine Fanatic not fluent with metric, as that's

what

the

How ever there is hope - I understand even Boeing is doing its

airliners

in

metric, ....or not?

Just to pick a little more .....3 grains to the inch, 12 inches to

the

foot,

3 feet to the yard, 2 yards to the fathom, 1 SM is 5280ft .....it

makes

sense!!
10 mm to the cm, 10 cm to the dm, 10dm to the meter, 1000 m to the
km........ how does that work???

I don't want to start with using fractions when using a caliper or

wrench

sizes or drill bit sizes ..........:))

Don't bother Thomas, we've tried to educate Paul on the metric system

By the way, Boeing is all Imperial. The US aviation industry is

probably

still the most  consistantly non-metric (although GE designs in

Metric, and

then bolts it all together with imperial fasteners).

Mark Wrathall.

"educate"? wow that is a real slam Mark :)

The metric system is fine for linear dimensions until you get into

stupid things

like Pascal, Hertz and Newton. The fact of the matter is the English

invented physics

and they got it right.

The metric system starts falling apart when you get into Newton's second

law.

F = m x a The metric system had to invent a new unit of force called the

Newton...

ironically. One Newton is = to 4.448221615260 pounds! One kilogram becomes

9.8  newtons while in the english system a pound is a pound. The concept of one
G is alien to the metric system. In the English system F = W x G

Paul Lamar

Isn't a pound just a slug times the acceleration due to gravity (in
Feet/sec2 ) times some bizarre constant?

Where is a pound a pound? On earth? The moon? Which part of the earth? Or is
a that a bushel? no wait....

1 pound is  4.3455 bushel cables per slug^2 right :)

Very coherent system. I like how Americans call it "Standard" :)

If man was meant to use the metric system, he would have been born with 10
fingers :)

Mark

What is not bizarre about 9.8 M/second^2 which replaces the slug in the metric system?

It is unitized  by the Newton. Have you every seen a bathroom scale calibrated
in Newton's? :) Do you really think you weigh the same number of kilograms 
anywhere in the universe? Nobody got to the moon on the metric system.
Almost all inventions we take for granted in the world where done with the
English system. Basically what happened is the English system won :)
Enough of this nonsense.
