What is a Joule (J)?
The Joule (J) is the SI unit of energy, work, and heat. It is defined as the energy transferred when a force of one newton moves an object one meter. Named after James Prescott Joule, it is the fundamental unit of energy in physics.
What is a Kilojoule (kJ)?
The kilojoule (kJ) is a unit of energy equal to 1,000 joules. It is commonly used in nutrition (particularly in Australia and Europe) and engineering for expressing energy content and transfer.
How to Convert Joule (J) to Kilojoule (kJ)
To convert Joule to Kilojoule, multiply the Joule value by 0.00100000. For example, to convert 5 Joule to Kilojoule: 5 × 0.00100000 = 0.00500000 Kilojoule. You can also use the free online calculator above for instant, accurate results.
