How Much Does A Cloud Weigh?


Have you ever wondered how much a cloud weighs?

Because they float so effortlessly, it would be easy to assume they are almost weightless. But, they are most certainly not.

According to scientists, the weight of the average cumulus cloud is 1.1 million pounds! Think about that for a moment. This means that at any given moment, there are millions of pounds of water floating above your head. That’s the equivalent of 100 elephants.

So, how does that much weight stay afloat? For one thing, the weight is spread out into millions of droplets over a really big space. Some of the droplets are so small that you would need a million of them to make a single raindrop.

How much would you have guessed a cloud weighed? Want to learn more about how scientists came up with the weight? Head over to Mental Floss for more on this cool story.

    Awesome. I didn’t know that a cloud weighed that much. By the way, I like chicken

  11. Awesome. I didn’t know that a cloud could weigh that much. By the way, i like chicken

  12. Well, there is 3.5896421501278e+20 (358,964,215,012,780,000,000 (358 quintillion)) gallons of water on Earth. So I would say that there could be as much as double that, or less then half of that, in the atmosphere of the entire planets atmosphere. (MATH) A cubic mile is equivalent to 147,197,952,000 (147 billion) cubic feet. Water weighs exactly 62.42718356 pounds per cubic foot. At said rate, a cubic mile of water would weigh 9.1891535691601e+12 (9,189,153,569,160.1) pounds. The total amount of water on the earth is about 326 million cubic miles of water. The total weight of Earths water would be 2.9956640635462e+21 (2,995,664,063,546,000,000,000 (2.995 sextillion)) pounds. One gallon of water weighs 8.3453 pounds. This means there is 3.5896421501278e+20 (358,964,215,012,780,000,000 (358 quintillion)) gallons of water on Earth.

  13. WHAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  14. Cool


  15. Not to sure I believe that. Is there actually an average cloud size. Look at them on an overcast day. None are the same or even that similar in size. Clouds appear to be random in size. And a cumulus cloud isn’t exactly a rain cloud. How much does a full blown cumulonimbus weigh?

  16. yea but how do you weigh it???

    It is cool that a cloud can weighs 1.1 million pounds! But why and how do they get that weight? I know they have water in them but that does not seem enough! Please reply I need answers!
