I don't know anyone who is afraid to walk underneath a cumulus cloud because they are afraid it might fall on them. We don't think of clouds even having weight because they are floating. But, clouds are made up of a physical substance, water, and water is quite heavy, so clouds must have weight. We will explain this "paradox" to you if you read on.
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.
