How to convert 1 kJ to joules

How to convert energy of 1 kilojoules (kJ) to joules (J).

The energy E in joules (J) is equal to 1 kilojoule times 1000:

E(J) = 1kJ × 1000 = 1000J

 

So 1 kilojoule (kJ) is equal to 1000 joules (J):

1 kJ = 1000 J

How do you convert from kJ to J?

kilojoule
Definition: The kilojoule is an SI (International System of Units) derived unit of energy that is equal to 1000 joules. Joule is defined as the amount of energy transferred to an object when a Newton force acts on an object in motion in a direction through a distance of one meter.

History/Origin: The kilojoule, like other SI derived units, uses SI prefixes to denote multiples or submultiples of a given unit. In this case, the prefix "kg" is used to express a multiple of 1000.

Current usage: In countries that have adopted the SI, the kilojoule is widely used as the unit of food energy. In some cases, both kilojoules and kilocalories are displayed, although in countries such as the United States, only kilocalories (often referred to as "calories") are shown on food labels. In addition to this everyday use, the kilojoule is used in scientific contexts around the world.
