What is Kilojoule?
The kilojoule (symbol: kJ) is a decimal multiple of the joule, the SI unit of energy.
One kilojoule is equal to 1,000 joules.
Common Uses
Kilojoules are commonly used to express the energy content of foods (as an alternative to calories) and in many engineering and industrial contexts to measure larger amounts of energy.
What is Joule?
The joule (symbol: J) is the base unit of energy in the International System of Units (SI).
It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force’s motion through a distance of one meter.
Common Uses
The joule is used in all fields of science and engineering to measure work, energy, and heat. It is a key unit in physics for calculating kinetic energy, potential energy, and thermal energy.
How many joule are in a kilojoule?
There are 1000 joule in 1 kilojoule.
