How Do You Convert kJ to kcal?

Kilojoules to Thermochemical / Food Kilocalories

1 kcal_th = 4.184 kJ

To convert energy from kilojoules (kJ) to kilocalories (kcal-th), you can use the following equation:

E_(kcal) = E_(kJ) / 4,184

Example

Convert 2000 kilojoules to kilocalories.

E_(kcal) = 2000 kJ / 4.1868 = 478.01147 kcal

Kilojoules to International Kilocalories

1 kcal_IT = 4,1868 kJ

The energy expressed in international kilocalories E_(kcal-IT) is equivalent to the energy measured in kilojoules E_(kJ), divided by a factor of 4,1868:

E_(kcal-IT) = E_(kJ) / 4,1868

Example

Convert 2000 kilojoules to kilocalories.

E_(kcal-IT) = 2000 kJ / 4.1868 =477.691793 kcal_IT

Kilojoules to 15°C Kilocalories

1 kcal₁₅ = 4.1855 kJ

The amount of energy in 15 degrees Celsius, measured in kilocalories E_(kcal15), can be determined by dividing the energy in kilojoules E_(kJ) by 4.1855.

E_(kcal15) = E_(kJ) / 4.1855

Example

Convert 15 kilojoules to kilocalories.

E_(kcal15) = 15 kJ / 4.1855 = 3.583801 kcal₁₅

Kilojoules to 20°C Kilocalories

1 kcal₂₀ = 4.182 kJ

The amount of energy measured in 20°C kilocalories, denoted as E_(kcal20), can be calculated by dividing the energy measured in kilojoules, denoted as E_(kJ), by the value 4.182:

E_(kcal20) = E_(kJ) / 4.182

Example

Convert 11 kilojoules to kilocalories.

E_(kcal20) = 11 kJ / 4.182 = 2.6303204 kcal₂₀
