The API gravity is an arbitrary scale developed by the American Petroleum Institute (API) as a measure of the density of petroleum liquids relative to the density of water. The values of API gravity are expressed as degrees API (°API).
Relationship between API gravity and specific gravity
The relationship between API gravity and specific gravity (SG) is mathematically expressed as:
- and where:
