Well, in Italy we use liters. One liter is one cubic decimeter, which is a SI unit. The only problem I see with metrication is aviation. One should change all instruments aboard planes, in control towers, and retrain all pilots. What a mess!

Not that difficult Tullio,
Distance and speed would change from nautical miles [1] to Kilometres and altitude from feet to metres. That's about it. Almost everything else is metric. It's been changing a bit a time, perhaps we should do away with the square rigged sailing ship terms first.
[1] nautical mile noun [C] (ALSO sea mile) a unit of distance used at sea which is equal to 1,852 metres.
Also, one litre = one kilogram of clean water. We can get volume by weighing it, we can fill tanks because we know the measurement (fish tank, 113cm x 65cm x 57.7cm = 423,806.5 cm3 = 423.8065 litres = 423.8065 kilograms extra weight. It's simple logical arithmetic).
Alas, NASA has only agreed to go metric for Moon missions in that decision, so 'tis not done by a long yard yet. :-(
Cheers, Mike.
Mike,
I have some reservations about NASA and Imperial measure. If memory serves, the Apollo was 330 feet tall and the capsule was designed to return 220 pounds of moon rock. There were other 'lucky' numbers but I don't recall them all now, but it appears America did go to the Moon in Metric after all.
Besides, von Brown didn't know feet, pounds and inches.
See this: SI
But what would happen if FAA went metric too?

I am just curious, Does anybody know what countries' air traffic control systems use metric units for aircraft seperation? I believe Russia and China do. I can't remember whether EuroControl does or not. I should knows this but it has been a long time

Well Apollo thirteen wasn't one... :-(

I thought that was the finest piece of work NASA ever did. The spacecraft blew up on the way to the moon and the crew still came back to Earth safely.
No body worried about other motives during that episode. ;-)
I believe you are exactly right. I don't believe human success is measured by the lack of failure, but by the ability to encounter failure, stare it in the eye, and make that potential failure, a success...

I'd agree in the ideal case, since any failure could bring success. But in practice, one should first look carefully at the risks as well, and base a good decision upon that assessment. I'd like to redefine your definition that human success is measured by the ability of judgement, and learning from errors in that judgement. And that could also mean turning a potential failure into success.

I believe Eurocontrol uses Imperial units, as all civilian aircrafts I know.
