TIL that the US spans about 10% of the Earth's circumference

The distance from Jacksonville, Florida to Los Angeles, California is about 3888 km. The earth's circumference is about 40 000 km (source), so the US spans about 10% of that, roughly :)

I always though "TIL" was "This is Lit!", until today, when I learned that was not the case.

That's driving distance. And if you're ignoring latitude and focusing on the lower 48 states, why not measure diagonally?

You need to follow the curve of the Earth in order to make such a comparison. You've drawn a random squiggly line on a Mercator map projection and took the length of that and compared it to the circumference of a sphere. Those two things simply cannot be compared like that.

The fact is still correct, the continental US is around 10% of the circumference. But in the grand scheme of things this isn't really important or relevant for anything? It's just a fun fact really. For example the country of Chile also spans about 10% of the circumference. And so does Australia. Russia approaches 20%.

As the circumference of the planet isn't a measurement a regular person can relate to, or has any meaning for anyone, what does this comparison give us in terms of a new insight?

Projection doesn't matter, distance remains consistent even if it appears longer or shorter than it is in reality.

That distance does follow the curve of the Earth. It necessarily must. Driving from Jacksonville to LA does not tunnel 3 miles beneath the surface of it earth.

well yeah chile is long but significantly longer than broad. for the US, the length/width ratio is more like 2:1 so it's less extreme.

and also yeah, australia is big, but mostly all desert (i guess 90%) while the US is only 50% desert.

You do know that on spheres there's more circumference angles than just east to west, right? Any direction also has a circumference on the surface of the Earth.

Technically Alaska is the eastern most and western most state, so it spans the entire earth.

TIL that half of the Canadian west coast is actually Alaska.

How big can we reasonably get this percentage? If we measure from Maine to the furthest tip of the Aleutian isles and take the circumference further north is that significantly larger? What if we go from Puerto Rico to Guam or American Samoa?

I only know about the French protectorates that play in concacaf -- do they also have some elsewhere? Otherwise it may not be much larger? Doesn't the Netherlands also have some far-flung colonies still?

Yes but France is the empire where the sun doesn't set. From Martinique over Réunion to French Polynesia in the Pacific, it basically spans the entire world.

At least some (maybe all?) of France's extra-continental territories are more like Hawaii than Guam. Their residents are full French citizens with proportional representation more or less equal to a section of European France with the same population.

France isn't the empire that the sun never sets on -- it's a single country that is near always in daylight.

True. It was a dig on the old saying about the British empire.

edit: the reason why i am posting that is because i knew that the US was pretty fucking big, but this just kinda puts numbers on the game, if you know what i mean.
