Oil gravity formula
WebbAPI gravity. API gravity is a commonly used index of the density of a crude oil or refined products.API stands for the American Petroleum Institute, which is the industry organization that created this measure.. Calculation of API gravity. API is calculated from a hydrocarbon's specific gravity using this formula:. API = (141.5/Specific Gravity) - 131.5 WebbSpecific Gravity or relative gravity is a dimensionless quantity that is defined as the ratio of the density of a substance to the density of the water at a specified temperature and is expressed as S G = ρ s u b s t a n c e …
