The scale was so firmly established that, by 1921, the remedy implemented by the American Petroleum Institute was to create the API gravity scale, recognizing the scale that was actually being used. [ 1 ]
The API gravity scale is a result of adapting to the subsequent errors from the Baumé scale. The Baumé scale is related to the Balling, Brix , Plato and ' specific gravity times 1000' scales. [ remove or clarification needed ]
API RP 500 and RP 505 classify the locations for electrical equipment in hazardous areas. [14] [15] API has entered petroleum industry nomenclature in a number of areas: API gravity, a measure of the density of petroleum. API number, a unique identifier applied to each petroleum exploration or production well drilled in the United States.
API gravity, universally used worldwide by the petroleum industry. Baumé scale, formerly used in industrial chemistry and pharmacology; Brix scale, primarily used in fruit juice, wine making and the sugar industry; Oechsle scale, used for measuring the density of grape must; Plato scale, primarily used in brewing

The clear cut definition of light and heavy crude varies because the classification is based more on practical grounds than theoretical. The New York Mercantile Exchange (NYMEX) defines light crude oil for domestic U.S. oil as having an API gravity between 37° API (840 kg/m 3) and 42° API (816 kg/m 3), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m 3 ...
The HuffPost/Chronicle analysis found that subsidization rates tend to be highest at colleges where ticket sales and other revenue is the lowest — meaning that students who have the least interest in their college’s sports teams are often required to pay the most to support them.
Here temperature is being specified using the current ITS-90 scale and the densities [5] used here and in the rest of this article are based on that scale. On the previous IPTS-68 scale the densities [ 6 ] at 20 °C and 4 °C are, respectively, 0.9982041 and 0.9999720 resulting in an RD (20 °C/4 °C) value for water of 0.99823205.
