Kcal to j Conversion Formula:
One Kilocalories is equal to 4184 Joule.
Formula: 1 kcal = 4184 J
By using this conversion factor, you can easily convert any energy from kilocalories to joule with precision.
How to Convert kcal to J?
Converting from kcal to J is a straightforward process. Follow these steps to ensure accurate conversions from kilocalories to joule:
- Select the Kilocalories Value: Start by determining the kilocalories (kcal) value you want to convert into joule (J). This is your starting point.
- Multiply by the Conversion Factor: To convert kilocalories to joule, multiply the selected kcal value by 4184. This factor is essential for accurately converting from a larger unit (kcal) to a much smaller unit (J).
- Illustration of Multiplication:
- 1 kcal = 4184 J
- 10 kcal = 41840 J
- 100 kcal = 418400 J
- Find the Conversion Result: The result of this multiplication is your converted value in joule unit. This represents the same energy but in a different unit.
- Save Your Joule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in joules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the kilocalories value by 0.0002390057361376673. This alternative method also gives you the correct energy in joules.
- Illustration of Division:
- J = kcal ÷ 0.0002390057361376673

Kilocalories to Joule Examples
Example 1:
Convert 0.4 Kilocalories to Joule.
Solution:
We know that one Kilocalories is equivalent to 4184 Joule.
Therefore,
0.4 kcal = 0.4 x 4184 J.
0.4 kcal = 1673.6 J.
Hence, 0.4 Kilocalories is approximately equal to 1673.6 Joule.
Example 2:
Convert 2 Kilocalories to Joule.
Solution:
We know that one Kilocalories is equivalent to 4184 Joule.
Therefore,
2 kcal = 2 x 4184 J.
2 kcal = 8368 J.
Hence, 2 Kilocalories is approximately equal to 8368 Joule.
Example 3:
Convert 88 Kilocalories to Joule.
Solution:
We know that one Kilocalories is equivalent to 4184 Joule.
