By far most of the water is in the oceans, which have an average depth of 3688m. 2% of the water is currently frozen, so one can easily estimate how much would the sea level raise, had it all melt.
EDIT: Corrected km to meters, as comment below points out.
I’m not saying it’s wrong, but this graphic is very difficult for me to understand. Is there any geographical significance to the location of the water blobs? No, right? But they also don’t include saltwater which is most of it. Right?
It also sort of explains how easy it would be for earth's water to have come from asteroid impacts.
