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.
Megajoules
A Megajoule (MJ) is a unit of energy equal to 1,000,000 joules. It is commonly used to measure large quantities of energy in various scientific, engineering, and industrial contexts. One megajoule represents the amount of energy required to apply a force of one newton over a distance of one million meters, or the energy transferred when one megawatt of power is applied for one second. Megajoules are often used to quantify the energy content of fuels, the work done by large machines, and the energy used or produced in industrial processes, providing a standard measure for comparing significant energy transfers and consumption.
