How much does sea water weigh per cubic foot?

Sea water has a typical density of around 64.1 pounds per cubic foot. This value is influenced by several factors, including temperature, salinity, and pressure, but for typical ocean conditions, 64.1 pounds per cubic foot is a standard reference. Understanding the weight of sea water is important for divers as it affects buoyancy and overall underwater dynamics.

The other potential weights provided are higher or lower densities that do not accurately reflect the average weight of sea water under most conditions found in oceans. Being familiar with this figure is essential for calculating buoyancy and understanding dive dynamics in various oceanic environments.
