A specific gravity scale developed by the American Petroleum Institute for measuring the relative density of various petroleum liquids, expressed in degrees. API gravity is gradated in degrees on a hydrometer instrument and was designed so that most values would fall between 10Â° and 70Â° API gravity. The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at 60Â°F) - 131.5, where SG is the specific gravity of the fluid.
