Kilojoules
A Kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is commonly used to measure energy in various scientific and engineering contexts, as well as in nutrition to quantify the energy content of foods. One kilojoule is the amount of energy required to apply a force of one newton over a distance of one kilometer, or the energy transferred when one kilowatt of power is applied for one second. Kilojoules are used in fields such as physics, chemistry, and engineering to quantify work, heat, and energy, providing a standard measure for comparing energy content and transfer across different systems and processes.
Joules
The Joule (J) is the SI unit of energy. One joule is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter. It can also be defined as the energy transferred when one watt of power is applied for one second. The joule is a versatile unit used in various scientific and engineering contexts to measure energy, work, and heat. It is commonly used in physics, chemistry, and engineering to quantify the energy content of fuels, the work done by machines, and the energy used or produced in electrical circuits.
