117 What is API Gravity of Crude Oil?

API gravity, short for American Petroleum Institute gravity, is a unit of measurement used to quantify the density of crude oil relative to water. It is expressed in degrees on the API gravity scale, which is an inverse scale where higher values indicate lighter and less dense crude oils, while lower values denote heavier and more dense crude oils. Among the various parameters used to characterize crude oil, API gravity stands out as a fundamental measure of its density and quality. The API gravity is a measure of the density of crude oil or petroleum liquids. API gravity is used to classify crude oils based on their density relative to water. Lighter crude oils have higher API gravity values, while heavier crude oils have lower API gravity values. An arbitrary scale expressing the gravity or density of liquid petroleum products. The measuring scale is calibrated in terms of degrees API; it is calculated as follows: Degrees API = (141.5 / (sp. gr. 60ºF / 60ºF)) - 131.5 The higher the API gravity, the lighter the compound. Light crudes generally exceed 38 degrees API and heavy crudes are commonly labeled as all crudes with an API gravity of 22 degrees or below. Intermediate crudes fall in the range of 22 degrees to 38 degrees API gravity.
