Downvoted for the use of ridiculous units
Comment on If you smoothened out the earth, 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 * r^3^ = 774,463,850,166 square miles.
332 miles^3^ / 774 miles^2 = 0.429 miles. I know I’m supposed to do 3D calculus but I don’t want to do that right now.

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.

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 they add unnecessary complexity with scientific or engineering applications

Should be r squared not cubed for area. I get ~1.7 miles or ~3km.

Fuck. Thanks for noticing it has been fixed

0.43mi is 0.69km
