Joule is the derived unit of the energy in the SI unit. It is defined by the energy system which is transferred to the object when one newton of force is equal to the power which is applied to the object in the direction of the motion from the distance of one meter. The unit of a joule is defined as the energy which is dissipated to the heat when the one ampere of electric current passes from a resistance of the one ohm, in the one second.

## J to kJ

The James Prescott Joule names the joule, he is a mathematician and the English physicist, and he is also helping to the development of the Kelvin scale. The joule is given the relationship between the heat and the mechanical work, which is leading by the law of the conservation of the energy, it is also subsequent, to the first law of the thermodynamics.

The unit kilojoule is also the international system unit which is the derived unit of the energy, and its value is equal to the one thousand joules. The unit joule is defined by the amount of the power which is transferred to an object when 1 newton of force is applied to an object in the direction of the motion from the distance of the 1 meter.

**Here are some conversion of the values of the joule into the kilojoule**

- The value of the 0.01 j is equal to the 0.0001 kJ, the value of the 1 J is equal to the 0.001 kJ
- The value of the 3 J is equal to the 0.003 kJ, the value of the 5 j is equal to the 0.005 kJ.
- The value of the 10 J is equal to the 0.01 J, the value of the 20 J is equal to the 0.02 kJ.
