The density of fresh water is approximately 1 kg/liter, or 1 tonne/cubic meter. That means that one liter of water weighs one kilogram. But salt water is denser, so heavier. Sea water averages about 1.027 kg/liter.

The Dead Sea, one of the saltiest seas in the world, has a density of 1.24 kg/L.

The water reaches saturation, about 35%, at 90 meters below the surface. Visit DeadSeaGuide.com

Note that these calculations don't allow for the salt dunes at the bottom, which have accumulated over centuries.

For the measurements of volume and salt content, see the Wikipedia link below. For a handy page to perform this type of calculation, see the link labelled "Volume Conversion."

Volume of the Dead Sea: 147 km3

Salt content by percentage: 33.7%

Salt content by volume: 147 * 33.7 / 100= 49.539 cubic kilometers= 49,539,000,000 kiloliters (25 trillion two-liter bottles)

Calculations by the English system (miles and gallons) are omitted because there exist at least three distinct units known as "gallon," none of which seems to be more relevant to the question than either of the others.

A gallon of water from the Dead Sea contains about 31.5% salt, but this fluctuates. It is 8.6 times saltier than the big seas and oceans. See Related Link(s) below ads for more details

The ocean's salinity varies depending on the area. In certain areas, the ocean can be close to 50 percent salt. Generally, the world's oceans are between 32 and 35 percent salt.
