WebDefinition. In 1994, the US National Institute of Standards and Technology (NIST) defined "gasoline gallon equivalent (GGE) [as] 5.660 pounds of natural gas." Compressed natural gas (CNG), for example, is a gas rather than a liquid. It can be measured by its volume in standard cubic feet (ft 3) at atmospheric conditions, by its weight in pounds (lb), or by its … WebIn accordance with the above, units like J/m³, J/L, kcal/m³, BTU/ft³ are used to measure several physical quantities that have much in common. They are used to measure the specific energy content of fuel per volume; the heat of combustion per volume; the volumetric energy density in a thermodynamic system.
