How many years of rain all over earth would it take to fill the oceans?

Answer 1

Depends on your rate of rainfall and what you are filling. The estimated total volume of water on the earth is 1,360,000,000 km³ with 97% the oceans. 1,320,000,000 km³. Since the average rainfall for many places is different here are a couple:

San Francisco, USA: 538 mm/year, 2,453,531,598,513 years

Sydney, Australia: 1222 mm/year, 1,080,196,399,345 years

London, England: 752 mm/year, 1,755,319,148,936 years

Basically between 1 and 3 trillion years, but we would have to assume that the rainfall rate would be much higher as the atmosphere would be saturated and it would slow down as the oceans filled. I would still assume it would be in the billions of years. Since the earth is only 4.5 billion years old it must have finished raining recently.

Answer 2

Rain comes from water of the ocean,so realistically, the ocean never fills, because rain is part of the cycle of the earth. The ocean never fills if you take the question literally.
