1.1 million pounds
How to measure the weight of a cloud
- How dense the cloud is = 1/2 gram per cubic meter
- How big the cloud is = a kilometer long and a kilometer tall.
- Do the math with the density and volume to determine the total water content of the cloud. In this case, it’s 500,000,000 grams of water, or 1.1 million pounds. Volume= Mass / Density
- How does a several-hundred-ton cloud stay afloat ? It’s distributed among trillions of tiny water droplets spread out over a really big space. Some of these droplets are so small that you would need a million of them to make one raindrop, and gravity’s effect on them is pretty negligible.
