Api gravity, английский
- A gravity scale established by the american petroleum institute and in general use in the petroleum industry, the unit being called "the a.p.i. degree." this unit is defined in terms of specific gravity as follows:
- Arbitrary scale expressing, in degrees api, the specific gravity of liquid petroleum products.
- Measures the density of petroleum fluids. it is derived from specific gravity and was developed to express density in whole numbers with one or two decimal places. for example, an api gravity of 25.5 is the same as a specific gravity of 0.9013. this does not compare to an h2o constant. this unit is defined in terms of specific gravity at 60°f (spg 60°f) as follows: degrees api 141.5 = spg 60° f - 131.5
