Joules to kilocalories conversion
Joules to kilocalories conversion is the process of converting energy values from joules (J) to kilocalories (kcal). To convert joules to kilocalories, you need to divide the value in joules by the conversion factor 4184.
What is Joules to kilocalories conversion
To convert joules (J) to kilocalories (kcal), you can use the conversion factor 0.000239006.
Kilocalories = J * 0.000239006
For example, let's convert 10,000 joules to kilocalories:
Kilocalories = 10,000 J * 0.000239006 Kilocalories ≈ 2.39006 kcal
Therefore, 10,000 joules is approximately equal to 2.39006 kilocalories.
How to convert from joules to kcal
Joules to thermochemical / food kilocalories
1 kcalth = 4184 J
The energy in joules E(J) is equal to the energy in kilocalories E(kcal-th) divided by 4184:
E(kcal) = E(J) / 4184
Example
Convert 5000 joules to kilocalories.
E(kcal) = 5000 J / 4184 = 1.195 kcal
Joules to international kilocalories
1 kcalIT = 4186.8 J
The energy in joules E(J) is equal to the energy in international kilocalories E(kcal-IT) divided by 4186.8:
E(kcal-IT) = E(J) / 4186.8
Example
Convert 5000 joules to kilocalories.
E(kcal-IT) = 5000 J / 4186.8 = 1.194 kcalIT
Joules to 15°C kilocalories
1 kcal15 = 4185.5 J
The energy in joules E(J) is equal to the energy in 15°C kilocalories E(kcal15) divided by 4185.5:
E(kcal15) = E(J) / 4185.5
Example
Convert 5000 joules to kilocalories.
E(kcal15) = 5000 J / 4185.5 = 1.195 kcal15
Joules to 20°C kilocalories
1 kcal20 = 4182 J
The energy in joules E(J) is equal to the energy in 20°C kilocalories E(kcal20) divided by 4182:
E(kcal20) = E(J) / 4182
Example
Convert 5000 joules to kilocalories.
E(kcal20) = 5000 J / 4182 = 1.196 kcal20
