What is the weight of a cubic foot of salt water?

A cubic foot of salt water typically weighs around 64 pounds. This weight is due to the density of salt water being greater than that of fresh water. The added salt increases the mass of the water, resulting in a higher weight per unit volume. In most scenarios, the commonly accepted weight for a cubic foot of seawater is approximately 64 pounds, which is essential information for divers to calculate buoyancy, equipment weight, and the overall dynamics of underwater movement. Understanding the weight of salt water is fundamental for safe and effective diving practices, allowing divers to make informed decisions regarding their gear and underwater activities.
