## Api Gravity, Density, and Specific Gravity - AmSpec Services

API gravity is another expression of this measurement that uses the Density/Specific gravity for its conversion. The higher the api the less dense the sample is. For example at 60°F: an api of 10.0 is equal to 1.0000 g/cm3. While an api of 80.0 is equal to 0.6684 g/cm3. Temperature is very important in relation to api and density.
