Kilojoules (kJ)
Definition
A kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is commonly used for expressing larger quantities of energy in nutritional contexts and engineering.
History
The kilojoule naturally derives from the joule with the SI kilo- prefix. It gained widespread use in the 20th century, particularly in countries adopting the metric system for food energy labeling.
Current use
Kilojoules are the primary energy unit on food labels in Australia, New Zealand, and many European countries. They are also used in heating, ventilation, and chemical energy calculations.
Electronvolts (eV)
Definition
An electronvolt (eV) is a unit of energy equal to the amount of kinetic energy gained by a single electron when accelerated through an electric potential difference of one volt. It equals approximately 1.602 × 10⁻¹⁹ joules.
History
The electronvolt emerged in the early 20th century with the development of particle physics and quantum mechanics. It provided a practical unit for describing atomic and subatomic energy scales.
Current use
Electronvolts are the standard unit in particle physics, nuclear physics, semiconductor physics, and quantum chemistry for expressing binding energies, photon energies, and particle masses.
