Clouds are of course suspended water droplets, or ice droplets depending on its elevation. A droplet is formed when water vapor condenses on some microscopic particle of dust, and only averages around 1/500 of an inch in diameter, small enough to float on air. But clouds tend to be big and all those droplets add up.
A meteorologist named Peggy LeMone figured out the weight of a typical cumulus cloud, which are those puffy white clouds that form on sunny days and look like popcorn or cauliflower. Since a ton is hard to visualize, LeMone compared a cloud’s weight to something more meaningful: elephants. A typical cumulus cloud weighs around 100 elephants, who weigh in at around 6 tons. Considering how many cumulus clouds you see on an average day, that’s a lot of elephants floating around.
The numbers are even more impressive for a storm cloud, the cumulonimbus type with a tall anvil shaped top and flat, dark bottom. Those can weigh in at 200,000 elephants. The largest storm cloud formation is a hurricane, which can pack a wallop of 40 million elephants, more than all the elephants on the planet. Now that’s a pack of pachyderms.
