one and five tenths, and is abbreviated °API. By definition, it reflects a special gravity at sixty degrees Fahrenheit (°API = 141.5/S.G. 60/60° –
131.5).
(c) ‘Cubic foot’ means the amount of liquefied petroleum product, vapor or natural gas vapor, or synthetic natural gas vapor, or any blend of the above, which will occupy one thousand seven hundred twenty-eight (1,728) cubic inches when its temperature is sixty degrees (60°) Fahrenheit at a pressure of seven hundred sixty (760) mm of Hg (mercury). The density of the Hg shall be 13.5951 grams per cubic centimeter per second, per second.
(d) ‘Guam standard petroleum measurement tables’ means procedures 11.1.6.1 and 11.1.6.2 within ASTM D1250-04 and API MPMS Chapter 11.1-2004/Adjunct to ASTM D1250-04 (ADJD1250CD).

(e) ‘Petroleum products’ include automotive gasoline; diesel fuels; fuel oils; liquefied petroleum gas (both liquid and vapor); residuals, distillates and fractions; kerosene; aviation fuels; turbine fuels; solvent; hydro-carbons or synthetics; crude oil; lubrication oil; or any other oil or distillates or blends of the above, or any other product or byproduct normally considered petroleum product and synthetic natural gas, or natural gas and manufactured gas or blends. This Section shall not apply to products sold in packages, such as motor oil sold in quart, liter or gallon containers; performance fuel additives; or engine cleaners.
(f) ‘U.S. petroleum gallon’ means that amount of petroleum product which occupies two hundred thirty-four point five (234.5) cubic inches exactly when its temperature is eighty-five degrees (85°) Fahrenheit, or the expanded or contracted equivalent thereto at any other temperature calculated using the observed temperature and observed API gravity.

(g) ‘Observed temperature’ means eighty-five degrees (85°) Fahrenheit.
(h) ‘Observed API gravity’ means fifty-three point one degrees
(53.1°).
