Specific Gravity
Specific Gravity is the ratio of the density of a substance to the density of a reference substance. In maritime context, the reference substance is usually fresh water. Specific gravity is an important parameter in ship stability calculations, as it determines the buoyancy of a ship. It is also used to determine the weight of cargo that can be loaded onto a ship, as well as the amount of ballast needed to maintain stability. Specific gravity is measured using a hydrometer, which is a device that measures the density of a liquid. The specific gravity of seawater varies depending on its salinity and temperature.
