the Atlantic Ocean is approximately 41.1 million sq miles (106 million sq km) in surface area without it's surrounding seas. It carriers a volume of approx. 77.64 million square miles. At about 62.427 lb per cubic foot at surface pressure. The weight of saline changes per cu foot based on absolute pressure ie the deeper you go, the more dense one cu foot of water will be so the more it will weigh, i do not have the information to calculate the density of the entire ocean. So at surface density one cu mile of sea water weighs about 4594563274.752 us tons. so i calculate that for the sake of casual conversation the approximate weight of the Atlantic ocean is 356,721,892,651,745,280 tons.
