Kilojoules to Calories (thermoc.) conversion formula
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 (thermoc.)
A thermochemical calorie, often abbreviated as cal_th, is a unit of energy that is primarily used in the field of chemistry. It is defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere, precisely defined as 4.184 joules.
