What is the density of Saltwater?

The density of saltwater is approximately 64 lbs/cubic ft. This value can vary slightly depending on factors such as temperature, salinity, and pressure, but 64 lbs/cubic ft is a widely accepted average for seawater at standard conditions. Understanding the density of saltwater is crucial in many marine applications, as it affects buoyancy, circulation patterns, and the behavior of marine organisms.

This density value contrasts with the densities of freshwater and other fluids, which are typically lower. In oceanographic and environmental studies, knowing the density of saltwater helps scientists and engineers calculate how objects will float, how currents will behave, and how sound propagates through the ocean, as sound generally travels faster in denser mediums.
