Do you Know – A cloud weighs around a million tonnes.
Posted by Vikas Acharya on January 23, 2026How can a cloud be that heavy?!
Even though clouds look light and fluffy, they’re made of tiny water droplets or ice crystals. There are a LOT of them.
A common example scientists use:
A typical fluffy cumulus cloud can contain:
- About 1 billion kilograms of water
- That’s ~1 million metric tonnes
Why it doesn’t fall out of the sky
- The droplets are microscopic
- Air resistance and updrafts keep them suspended
- When droplets grow big enough → rain
Bigger clouds = even heavier
- Large storm clouds (cumulonimbus) can weigh several million tonnes
