By “smoothing out” I mean flattening all mountains and filling all trenches so that the entire earth has exactly the same radius everwhere. Water naturally spreads out equally on such a surface, so how high would the water level be?

So there’s 332,519,000 cubic miles of water on the planet approxomately
The earth has a radius of 3,950 miles
That leaves a surface area of 4 * pi * r2 = 196,066,797 square miles.
332 miles3 / 196 miles2 = ~1.7 miles I know I’m supposed to do 3D calculus but I don’t want to do that right now and the difference in radius is negligible,
0.43mi is 0.69km
Thank you for using the same money of significant digits.
Nice
Should be r squared not cubed for area. I get ~1.7 miles or ~3km.
Fuck. Thanks for noticing it has been fixed
Downvoted for the use of ridiculous units
Ahaha. All the people from the US downvoting this 🤦♂️ So many solutions to questions like this a just easier and more intuitive in metric. Tec diving is just hilarious in imperial units
I’m fine with imperial units, as long as somebody stays in one unit system and doesn’t mix miles, yards, feet and inches, or square miles and acres, etc.
Yeah, I’m fluent in what you listed too… but everything you listed is just meters in metric so that’s five-ish conversions to needlessly need to know. And if you start using equations in then standard units play up a lot like when diving with imperial units you measure depth in feet but pressure in pounds per square inch so you have an awkward feet to inch right there and the equations are just more complicated. Anything beside the simple gets compounding unit conversions. And the countries left in the world that only use imperial are the US, Myanmar and Liberia.
Definitely. But fortunately, everything here has the dimension length to the power of something.
Like, nautical miles have a good use but that’s not even the miles being used
Imperial units are fine. They have rational conversion ratios between them and standard metric. I was in bed at the time and miles is what I got from search results.
Sure, they’re great for people chatting casually in the US, Myanmar and Liberia but even there they still add unnecessary complexity with scientific or engineering applications
OK
You did well in your answer by the way. I didn’t downvote. My comments are directed at everyone downvoting the person calling out imperial units
