I love how you're mixing metric and imperial in the title 😂

TIL some people think 1 cubic kilometer is "small"

1 cubic kilometer of anything will basically fucking kill you.

What about 1 cubic km of air at one standard atmospheric pressure?

It may take a hundred years, but it will kill you.

For reference: air density is roughly 1kg/m³ [see note]. So the same volume of air is roughly 10⁶ tons. The air in the cloud weights 2000 more than the water.

NOTE: it's 1.3kg/m³ on sea level, 0.9kg/m³ at 3km over sea level, I think that 1kg/m³ is a safe bet.
