The density of the oil is a fundamental physical property that dictates how it behaves in storage, transport, and refining processes. In maritime shipping, the density determines the vessel's displacement and stability; tanks must be loaded to a "heel" that keeps the ship balanced in the water.

The API value inversely correlates with the specific gravity, meaning a higher API number indicates a lighter, more valuable crude. These measurements are always reported at a standardized temperature, usually 15°C (60°F) or 20°C (60°F), because the fluid expands when warm and contracts when cold.
Commercial and Economic Significance Beyond technical parameters, the density of the oil is a commercial differentiator that affects pricing and market value. This variation is not merely academic; it directly influences how the fluid flows, separates in tanks, and reacts during processing.

Heavy vacuum residues with very high density are processed into residual fuels or sent to coking units to produce lighter products. The Relationship Between API Gravity and Density In the energy sector, density is frequently communicated through the American Petroleum Institute (API) gravity scale.
