API Gravity

API gravity: A specific gravity scale formulated by the American Petroleum Institute (API) for calculating the relative density of numerous petroleum liquids, indicated in degrees. API gravity is gradated in levels on a hydrometer device and was created so that most values would fall around 10° and 70° API gravity. The arbitrary method applied to get this result is: API gravity = (141.5/SG at 60°F) – 131.5, where SG is the specific gravity of the fluid. See API gravity calculation.
