Small & large calories
Small calorie (cal) is the energy needed to increase 1 gram of water by 1°C at a pressure of 1 atmosphere.
Large calorie (Cal) is the energy needed to increase 1 kg of water by 1°C at a pressure of 1 atmosphere.
Large calorie is also called food calorie and is used as a unit of food energy.
How to convert from kilojoules to calories
Kilojoules to thermochemical calories
1 calth = 0.004184 kJ
1 kJ = 239.0057 calth
The energy in thermochemical calories E(calth) is equal to the energy in kilojoules E(kJ) times 239.0057:
E(cal) = E(kJ) × 239.0057
Convert 0.6 kilojoules to thermochemical calories.
E(cal) = 0.6kJ × 239.0057 = 143.4 calth
Kilojoules to 15°C calories
1 cal15 = 0.0041855 kJ
1 kJ = 238.9201 cal15
The energy in 15°C calories E(cal15) is equal to the energy in kilojoules E(kJ) times 238.9201:
E(cal15) = E(kJ) × 238.9201
Convert 0.6 kilojoules to 15°C calories.
E(cal15) = 0.6kJ × 238.9201 = 143.352 cal15
Kilojoules to large/food calories
1 Cal = 4.184 kJ
1 kJ = 0.239 Cal
The energy in large/food calories E(Cal) is equal to the energy in kilojoules E(kJ) times 0.239:
E(Cal) = E(kJ) × 0.239
Convert 0.6 kilojoules to food calories.
E(Cal) = 0.6kJ × 0.239 = 0.1434 Cal
