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?

As @huquad@lemmy.ml pointed out, @LodeMike@lemmy.today had an error in their calculation (radius squared instead of cubed). Their corrected result, 1.7 mi also equals 2.7 km (rounding to 3 km is a bit rough).
My answer is also based on some pretty rounded figures and I’d had a few drinks before doing that math.
2 miles is roughly 3.2km. Honestly, the fact that I’m even within the same order of magnitude as the other answers is surprising.
