Source and calculation

Estimated 420,500 km³ per year ÷ year seconds × 60

We divide the USGS annual central estimate of 420,500 km³ by the seconds in a 365-day year. One km³ is a cube one kilometre on each side.

How to read this number

The source range is broad: 350,000–510,000 km³ a year. Evaporation is not evenly spread across seasons or places.

Scope and caveat

The source range is 350,000–510,000 km³ per year. Actual evaporation varies by season and year.
