KiloCalories and KiloJoules.
The unit of energy found on food packets is typically measured in kilocalories (kcal) or kilojoules (kJ). Kilocalories are more commonly used in the United States, while kilojoules are more common in other countries. One kilocalorie is equivalent to 4.184 kilojoules.

The unit used on food packets that equals 1000 joules is called a kilojoule (kJ). It is commonly used to measure the energy content of foods and beverages. One kilojoule is equivalent to 1,000 joules, and nutrition labels often provide energy values in kilojoules alongside or instead of calories.
The term for the small packets of energy emitted from light is photons. Photons are the basic unit of light and possess characteristics of both particles and waves. They carry energy and momentum and are responsible for electromagnetic interactions.
