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