Water Scale Explorer
There's a lot of water on Earth. Almost none of it is water you could drink. Tap into the beaker below to see exactly where it all goes.
All the water on Earth
Tap a slice of the beaker to learn what it is.
Figures are approximate, rounded for clarity, and based on commonly cited USGS / UNESCO water-distribution estimates.
Put it in perspective
Imagine every drop of water on Earth filling a 4-litre jug. Almost all of it — oceans, ice, deep groundwater — you'd never touch. The water in lakes and rivers you could actually drink or farm with? Roughly one teaspoon out of the whole jug.
Quick check
Three questions. No pressure.
About the Water Scale Explorer
This tool visualizes how Earth's water is actually distributed — from the vast, undrinkable ocean down to the sliver of surface fresh water people rely on. Tap any layer of the beaker to zoom in and see what makes it up, based on commonly cited USGS and UNESCO estimates.
Why can't we just drink ocean water?
Ocean water is far too salty for the human body to process — drinking it dehydrates you faster than not drinking anything at all.
How accurate are these percentages?
They're widely cited, rounded estimates from sources like the USGS and UNESCO. Exact figures vary slightly between studies, but the overall picture is consistent.
