How to convert from kilojoules to kcal
Kilojoules to thermochemical / food kilocalories
1 kcalth = 4.184 kJ
The energy in kilocalories E(kcal-th) is equal to the energy in kilojoules E(kJ) divided by 4.184:
E(kcal) = E(kJ) / 4.184
Example
Convert 5 kilojoules to kilocalories.
E(kcal) = 5 kJ / 4.184 = 1.195 kcal
Kilojoules to international kilocalories
1 kcalIT = 4.1868 kJ
The energy in international kilocalories E(kcal-IT) is equal to the energy in kilojoules E(kJ) divided by 4.1868:
E(kcal-IT) = E(kJ) / 4.1868
Example
Convert 5 kilojoules to kilocalories.
E(kcal-IT) = 5 kJ / 4.1868 = 1.194 kcalIT
Kilojoules to 15°C kilocalories
1 kcal15 = 4.1855 kJ
The energy in 15°C kilocalories E(kcal15) is equal to the energy in kilojoules E(kJ) divided by 4.1855:
E(kcal15) = E(kJ) / 4.1855
Example
Convert 5 kilojoules to kilocalories.
E(kcal15) = 5 kJ / 4.1855 = 1.195 kcal15
Kilojoules to 20°C kilocalories
1 kcal20 = 4.182 kJ
The energy in 20°C kilocalories E(kcal20) is equal to the energy in kilojoules E(kJ) divided by 4.182:
E(kcal20) = E(kJ) / 4.182
Example
Convert 5 kilojoules to kilocalories.
E(kcal20) = 5 kJ / 4.182 = 1.196 kcal20
