Definition of energy (KJ to cal) :
A quality of matter that enables it to perform work is energy. Due to its scalar nature, it has simply magnitude and no direction.. Energy can exist in many different forms, including kinetic energy (energy of motion).kinetic energy (energy of position). and thermal energy (energy of heat). chemical power (energy stored in chemical bonds). and electromagnetic energy (energy of light and other electromagnetic waves).ALSO:
- kinetic energy: The force behind the motion. such as the energy of a moving object.
- Potential energy: The energy of position. such as the energy stored in an object due to its position in a gravitational field.
- Thermal energy: The energy of heat. such as the energy of a hot object.
- Chemical energy: The energy stored in the chemical bonds of atoms and molecules, such as the energy in gasoline that powers a car engine.
- Electromagnetic energy: The energy of light and other electromagnetic waves, such as the energy of sunlight or radio waves.
- Nuclear energy: The energy stored in the nucleus of atoms, such as the energy released during nuclear reactions.
- Conventional and Non-conventional energy: Classification of energy into conventional and non-conventional based on their sources and usage.

Kilojoules (KJ) and calories (cal) are units that are commonly used to measure energy in the context of food and nutrition.Joules (J):
The base unit of energy in the International System of Units (SI). it is used to measure a wide range of energies. It is defined as the amount of energy required to move an electric charge of one coulomb through an electric potential difference of one volt.
Kilojoules (KJ):
A unit of energy, which is equal to 1000 Joules. It is commonly used to measure the energy content of food and the energy expenditure of physical activity.
Calories (cal):
