How to convert from kcal to kilojoules

Thermochemical / food kilocalories to kilojoules

1 kcal_th = 4.184 kJ

The energy in kilojoules E_(kJ) is equal to 4.184 times the energy in thermochecmical / food kilocalories E_(kcal):

E_(kJ) = 4.184 × E_(kcal)

Example

Convert 0.3 kcal_th to kilojoules.

E_(J) = 4.184 × 0.3 kcal_th = 1.2552 kJ

International kilocalories to kilojoules

1 kcal_IT = 4.1868 kJ

The energy in kilojoules E_(kJ) is equal to 4.1868 times the energy in international kilocalories E_(kcal-IT):

E_(kJ) = 4.1868 × E_(kcal-IT)

Example

Convert 0.3 kcal_IT to kilojoules.

E_(kJ) = 4.1868 × 0.3kcal_IT = 1.25604 kJ

15ºC kilocalories to kilojoules

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_(kJ) = 4.1855 × E_(kcal15)

Example

Convert 0.3 kcal₁₅ to kilojoules.

E_(kJ) = 4.1855 × 0.3kcal₁₅ = 1.25565 kJ

20ºC kilocalories to joules

1 cal₂₀ = 4.182 J

The energy in kilojoules E_(kJ) is equal to 4.182 times the energy in 20ºC kilocalories E_(kcal20):

E_(kJ) = 4.182 × E_(kcal20)

Example

Convert 0.3 kcal₂₀ to kilojoules.

E_(kJ) = 4.182 × 0.3kcal₂₀ = 1.2546 kJ
