Are we talking about the backwater country that everyone seems to want
to move to without an invitation?

Yeah, yeah, I know. Parochial and childish, but it is what it is. I personally use both systems interchangeably.

So at the present time, the "English" measurements are used in, uhh, Liberia, Myanmar and the US. Runnin' with the Big Dogs!

All the Metric system does is throw out a bunch of units which over centuries were developed because they were useful. We could convert the Imperial system to 'metric' the same way: every weight would be quoted in ounces, every measurement in inches. Done. But not really useful. A mile would become 63 Kinches. Gliders would weigh 18.512 Kounces, rather than 1157 pounds. And the world would think us brilliant. But a mile is actually a useful unit, in context, as is a pound and a ton.

One degree of latitude is 60 nautical miles, and one minute is a nautical miles which is 6000 feet. Makes for some easy math measuring distance on a chart.

Not as simple using the metric system...

On 1:500 000 scale charts 1 cm represents 5km exactly. 1 inch more or less 8 miles.
On 1: 1000000 scale charts 1 cm represents 10km exactly 1 inch more or less 16 miles.

.... But you then have to carry a ruler with you in the cockpit or do you
have a body part that measures centimeters, e.g., the middle bone in my
little finger is very close to 1 inch so it's easy to approximate inches
on a chart, but why bother when I can simply use the minute marks to
estimate distance?Â* It is, therefore easy to see that 1 degree is 1.852
km.Â* Did you bring a calculator?

It's snowing outside... :-(

Mark and 'Anonymus': the metric system is used in all of science, check it out. Remember the failed Mars shot some 30-40 years ago? The clear cause of conversion factor errors. Dan, don't forget your metric tool set when flying your beautiful Stemme!

Less than 20 years https://en.wikipedia.org/wiki/Mars_Climate_Orbiter .

I have both kinds of tools.Â* It's maddening to need a metric wrench on a
Harley Davidson.Â* Frankly I have no grief with the metric system other
than the fact that, being raised with the "moon" system, I can visualize
the measurements.Â* I can look at an SAE nut and tell you that it's 3/8,
1/2, 9/16 inches, but I can't do the same with 6, 8,10,12 mm.Â* Just what
I'm used to.

I think the gliding community likes the metric system because 1,000 km
sounds more impressive than a mere 621.3712 miles, and way better than
539.9555 nautical miles.
