OK the two things still commonly measured or specified in inches workdwide are:

Tyres (hence wheels - a mark to Andy) - rim diameter in inches (pouces or zoll)

Chains (whether bicycle, cam, or ship anchor) - pitch is in inches

Bar is neither metric (SI) nor imperial, it simply is 1 atmosphere (at STP). However it is almost metric, as 1 bar is almost exactly 100 kilopascals (kPa), the SI unit of pressure. In imperial, one bar is 15 pounds per square inch or 34 feet of sea water (interestingly, again almost metric as this is close to 10m!)

Most calculations are easier in metric, and the sooner we all accept them the better IMVHO.

The USA, of course, is moving towards metrication inch by inch...

Andy,
OK I confess. They are my initials: Gerwyn LLoyd Hywel Griffiths

Welsh has a strange alphabet and 'LL' is actually a letter.

I am now going to change my name to John Smith!! hide

Nigel,
re the last line of your post. I take it, in the language of former President George W Bush, you mean that
" epistemologically-wise speaking" !!

the european airspace is even more confusing... when crossing the border up in the air with CZ for example, one has to use meters instead of feet for altimeter heigt indication and altimeter setting (pressure) is given in hectopascal instead of mb... and instead of nautical miles the distances are in kilometers..

herman,

if I remember correctly, confusion in the air is not restricted to Europe.

A pilot friend reported that in the USA the air traffic control has abandoned the nautical mile (good) and introduced the terrestrial mile banghead as unit for distances and as basis for speed.

Consequently, someone reported the airplane speed in "mph" to ground control. In return they asked something like:
"... and what is that in knots?"

His response:
"What do I know, I´m flying, not sailing!"

Andy.

"USA ATC has abandoned the nautical mile (good)"

No, that's not good; the reason for using the nautical mile in navigation is that it is one minute of longitude and so can be read directly off a chart using calipers from the North-South axis. So there are 180 x 60 = 10,800 nm on a great circle connecting the poles. No matter where in the world you are this is a standard; it is a basic navigational unit and is not superseded by GPS. A GPS does not care what units you use, whether km, statute or nautical miles - pushing a button does the conversion and it changes nothing else!

The only reason it is called "nautical" is historical, as it was defined before air travel was conceived.

Basic pilot training (PPL etc) includes learning the realtionship between, and how to convert between, nautical and statute - and if a fully trained and highly paid commercial pilot can't do that we are all doomed!

Me too, althought I´m "boatless" at the moment.

And I agree that the nautical mile being 1 arc minute of a great circle is somewhat related to reality. It just doesn´t fit into the SI scheme.

re: fuel tank... still got no definitive answer on the exact capacity of my 4/78 +/4... last sunday december 6- we drove the "winter games" tour run in northern France and managed to do 211 miles with 32 liters... lucky to get home with the same fuel tank, because in the very remote area around St-Pol & Bethunes no "gasolineras" were open for service on sundays, even with banccards it was a no-go on the scarsely found ones- but we dared and managed to get home, our courage was strong because we carried a spare canister with 4.5 lt extra "benzina" along...

Herman, according to the "Owners Handbook" of 1977 Tank capacity for the

4/4 4-seater is 10 gallons/45 litres/12 US-gallons.

For the 2-seater it is 8.5 gallons/39 litres/10 US-gallons.

97 Octane minimum!

Hope this helps.
