What is the weight of seawater per cubic foot?

The weight of seawater per cubic foot is approximately 64 pounds. This value takes into account the average salinity and temperature of seawater, which affects its density. Seawater is denser than freshwater due to the dissolved salts, which increases its weight.

Understanding this measurement is crucial for various applications in underwater activities, including buoyancy calculations, diving physics, and marine engineering, as it helps divers and engineers determine how much weight is needed to achieve neutral buoyancy or how structures interacting with water will behave under different conditions.

While freshwater weighs about 62.4 pounds per cubic foot, the greater density of seawater, typically around 64 pounds per cubic foot, is an important factor to remember when working in marine environments.
