About Units

Kilojoules: Kilojoules (kJ) are equal to 1,000 joules. This unit is often used in fields such as chemistry and nutrition to quantify energy. For example, food energy is commonly expressed in kilojoules per serving or per 100 grams.

Megajoules: Megajoules (MJ) are equal to 1,000,000 joules. This unit is commonly used to describe large quantities of energy, such as the energy content of fuels, electrical energy, and the energy output of engines.
