How to convert from kcal to kilojoules

The Thermochemical / food kilocalories to kilojoules

3 kcalth = 12.552 kJ

so 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-th)

Example 1

Convert 0.4 kcalth to kilojoules.

E(kJ) = 4.184 × 0.4 kcalth = 1.6736 kJ

Example 2

Convert 0.6 kcalth to kilojoules.

E(kJ) = 4.184 × 0.6 kcalth = 2.5105 kJ

Example 3

Convert 0.8 kcalth to kilojoules.

E(kJ) = 4.184 × 0.8 kcalth = 3.3472 kJ

International kilocalories to kilojoules

2 kcalIT = 8.3736 kJ

so 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 1

Convert 0.4 kcalIT to kilojoules.

E(kJ) = 4.1868 × 0.4kcalIT = 1.67472 kJ

Example 2

Convert 0.5 kcalIT to kilojoules.

E(kJ) = 4.1868 × 0.5kcalIT = 2.0934 kJ

Example 3

Convert 0.8 kcalIT to kilojoules.

E(kJ) = 4.1868 × 0.8kcalIT = 3.34944 kJ

15°C kilocalories to kilojoules

2 kcal15 = 8.371 kJ

The energy in kilojoules E(kJ) is equal to 4.1855 times the energy in 15°C kilocalories E(kcal15):

E(kJ) = 4.1855 × E(kcal15)

Example 1

Convert 0.2 kcal15 to kilojoules.

E(kJ) = 4.1855 × 0.2kcal15 = 0.8371 kJ

Example 2

Convert 0.5 kcal15 to kilojoules.

E(kJ) = 4.1855 × 0.5kcal15 = 2.09275 kJ

Example 3

Convert 0.9 kcal15 to kilojoules.

E(kJ) = 4.1855 × 0.9kcal15 = 3.76695 kJ

20°C kilocalories to kilojoules

2 cal20 = 8.364 kJ

so energy in kilojoules E(kJ) is equal to 4.182 times the energy in 20°C kilocalories E(kcal20):

E(kJ) = 4.182 × E(kcal20)

Example 1

Convert 0.4 kcal20 to kilojoules.

E(kJ) = 4.182 × 0.4kcal20 = 1.6728 kJ

Example 2

Convert 0.5 kcal20 to kilojoules.

E(kJ) = 4.182 × 0.5kcal20 = 2.091 kJ

Example 3

Convert 0.9 kcal20 to kilojoules.

E(kJ) = 4.182 × 0.9kcal20 = 3.7638 kJ
