Salinity to Density Calculator

Salinity affects water density. As salinity increases, water becomes denser. This relationship is more pronounced when combined with lower temperatures, making cold, salty water denser than warm, less salty water. Consequently, oceanic regions with higher salinity tend to have denser seawater, impacting ocean circulation and ecosystem dynamics.
