Sea water weighs how many kilograms per liter and how many pounds per cubic foot?

Explanation:
Density is what you’re looking at here—the mass per unit volume of seawater. At typical seawater salinity, its density is about 1.025 kilograms per liter. To put that in pounds per cubic foot, use the conversion 1 kilogram per liter ≈ 62.43 pounds per cubic foot. Multiplying gives roughly 64.0 pounds per cubic foot. So seawater weighs about 1.025 kg/L and about 64 lb/ft^3. (Freshwater is about 1.000 kg/L, ~62.4 lb/ft^3, which is why seawater is noticeably denser.)
