Kilocalories to kilojoules conversion
Kilocalories to kilojoules (kJ) conversion is the process of converting energy values from kilocalories (kcal) to kilojoules. To convert kilocalories to kilojoules, you need to multiply the value in kilocalories by 4.184.
What is Kilocalories to kilojoules conversion
To convert kilocalories (kcal) to kilojoules (kJ), you can multiply the value in kilocalories by 4.184.
kJ = kcal * 4.184
For example, let's convert 100 kilocalories to kilojoules:
kJ = 100 kcal * 4.184 kJ = 418.4 kJ
Therefore, 100 kilocalories is equal to 418.4 kilojoules.
How to convert from kcal to kilojoules
Thermochemical / food kilocalories to kilojoules
1 kcalth = 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-th)
Example
Convert 0.3 kcalth to kilojoules.
E(kJ) = 4.184 × 0.3 kcalth = 1.2552 kJ
International kilocalories to kilojoules
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(kJ) = 4.1868 × E(kcal-IT)
Example
Convert 0.3 kcalIT to kilojoules.
E(kJ) = 4.1868 × 0.3kcalIT = 1.25604 kJ
15°C kilocalories to kilojoules
1 kcal15 = 4.1855 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
Convert 0.3 kcal15 to kilojoules.
E(kJ) = 4.1855 × 0.3kcal15 = 1.25565 kJ
20°C kilocalories to kilojoules
1 cal20 = 4.182 kJ
The 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
Convert 0.3 kcal20 to kilojoules.
E(kJ) = 4.182 × 0.3kcal20 = 1.2546 kJ
