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
