Joule/Kilogram

The joule per kilogram (J/kg) is the SI unit of specific energy or fuel efficiency per unit mass. It represents the amount of energy released or consumed per kilogram of fuel. It is used in thermodynamics and fuel science to compare the energy content of different materials on a mass basis. 


Btu (th)/Pound

The thermochemical British thermal unit per pound (Btu(th)/lb) is based on the thermochemical BTU, which equals 1054.35 J. Slightly different from the IT Btu/lb, it is used in thermochemistry for precise calorimetric calculations involving solid and liquid fuels.
