How heavy are the clouds?

The clouds we see in the sky seem rather light, almost like absorbent cotton. However, being filled with water and ice, these gigantic suspended masses weigh - in reality - up to several tons. Don't be fooled by appearances, the clouds that float above your heads are more like anvils in suspension. Indeed, being made of billions of water and ice droplets, these vaporous masses can weigh far more than you may expect. With a water density of about 0.5 grams per cubed meter, a cloud of 100 kilometers cubed can reach the mass of 500 000 tons. See for privacy and opt-out information.
