Reverse All Units

Converting between calories and kilojoules is essential in physics, nutrition, electrical engineering, and heating calculations. Energy units bridge different domains: joules in physics, calories in nutrition, kilowatt-hours in electricity, and BTUs in heating.

Also convert to: J kJ MJ kcal Wh kWh BTU

0 cal = 0 kj

0 (zero) calorie(s) is equal to 0 (zero) kilojoule(s)

What is calorie?

The calorie (cal) equals 4.184 joules. It was originally defined as the energy needed to raise one gram of water by one degree Celsius. Small calories are used in chemistry and physics.

What is kilojoule?

The kilojoule (kJ) equals 1,000 joules. It is used in nutrition labelling in many countries and for measuring the energy content of foods, chemical reactions, and industrial processes.
