Kilojoules to Calories (Kilogram,thermoc.)

Kilojoules

A kilojoule (kJ) is equivalent to one thousand joules (J). It is the energy required when a force of one thousand newtons is applied over a distance of one meter, or one newton applied over a kilometer. In reality, a joule is roughly the energy required to lift a small apple one meter against Earth's gravity.

Calories (Kilogram,thermoc.)

The kilogram calorie (also known as the large calorie, food calorie, or kilocalorie) is the energy to raise the temperature of one kilogram of water by one degree Celsius at a pressure of one atmosphere. This unit is widely used in nutrition to quantify the energy content of foods.
