How much salt does the sea contain?

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
