Small & large calories

Small calorie (cal) is the energy needed to increase 1 gram of water by 1ºC at a pressure of 1 atmosphere.

Large calorie (Cal) is the energy needed to increase 1 kg of water by 1ºC 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

kJ to thermochemical calories

1 cal_th = 0.004184 kJ

1 kJ = 239.0057 cal_th

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

Example

Convert 0.6 kilojoules to thermochemical calories.

E_(cal) = 0.6kJ × 239.0057 = 143.4 cal_th

kJ to 15ºC calories

1 cal₁₅ = 0.0041855 kJ

1 kJ = 238.9201 cal₁₅

The energy in 15ºC calories E_(cal15) is equal to the energy in kilojoules E_(kJ) times 238.9201:

E_(cal15) = E_(kJ) × 238.9201

Example

Convert 0.6 kilojoules to 15ºC calories.

E_(cal15) = 0.6kJ × 238.9201 = 143.352 cal₁₅

kJ 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

Example

Convert 0.6 kilojoules to food calories.

E_(Cal) = 0.6kJ × 0.239 = 0.1434 Cal
