What is a KiloJoule (kJ)?
A kilojoule (kJ) is a unit of energy in the International System of Units (SI), equal to 1,000 joules (J). A kilojoule is a measure of the amount of work done or heat transferred. KiloJoules are used throughout physics, chemistry, engineering, and for nutrition labeling.
What is a Joule (J)?
A joule (J) is the standard unit of energy that measures work, heat, or power transferred. One joule is equal to the energy transferred when an object is moved one meter by the application of one newton of force.
In simple terms: 1 KiloJoule = 1,000 Joules
KiloJoules to Joules Conversion Formula
The conversion from KiloJoules to Joules is simple and exact:
J = kJ x 1000
Example:
If you have 2.5 kJ, multiply it by 1000 to get 2500 J.
2.5 x 1000 = 2500J
This KiloJoules to Joules converter performs this calculation instantly and precisely every time.
