Key Terminology
- Kilogram per joule (kg/J)
- A unit expressing how much mass is required to provide one joule of energy; it is the reciprocal of specific energy (J/kg).
- Kilogram per kilojoule (kg/kJ)
- A unit measuring the mass needed for one kilojoule of energy; it is the reciprocal of specific energy in kilojoules per kilogram (kJ/kg).
- Specific energy
- The amount of energy per unit mass, often expressed as joules per kilogram (J/kg) or kilojoules per kilogram (kJ/kg).
