### API Gravity FSC 432:Petroleum Refining

API Gravity Density is defined as mass per unit volume of a fluid. The density of crude oil and liquid hydrocarbons is usually reported in terms of specific gravity (SG) or relative density, defined as the density of the liquid material at 60°F (15.6°C) divided by the density of liquid water at 60°F. API gravity Oilfield GlossaryAPI gravity is gradated in degrees on a hydrometer instrument and was designed so that most values would fall between 10° and 70° API gravity. The arbitrary formula used to obtain this effect is:API gravity = (141.5/SG at 60 degF) 131.5, where SG is the specific gravity of the fluid.

Density is the mass of material per unit volume. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 o C. Because specific gravity is a ratio, it is a unitless quantity. Density to Specific Gravity CalculatorSG = Specific gravity (e.g. pure water = 1) Density of Substance () This is the measure of the amount of mass per unit volume of a substance. The density is derived by dividing the mass of a quantity of substance by its volume. Specific Gravity of Substance (SG) This is the ratio of the density of a substance compared to the density of pure

The relation between API gravity and relative density (formerly called specific gravity) is:API Gravity at 60 Deg. F. = (141.5 :Relative Density 60F/60F) 131.5. ASTM:American Society for Testing Materials. Grade and quality specifications for petroleum products are determined by ASTM test Water - Specific Gravity - Engineering ToolBoxSpecific gravity (SG) for water is given for four different reference temperatures (39.2, 59, 60 and 68°F). From 32 to 212°F the pressure is 14.7 psi, and for temperatures >212°F, the pressure is equal to water saturation pressure. Density - Density of different solid materials, liquids and gases. What is Specific Gravity? - Definition, Formula Oct 01, 2020 · The specific gravity of an object is the ratio between the density of an object to a reference liquid. Usually, our reference liquid is water , which has a density of 1 g/mL or 1 g/cm^3.
