Formula: 1 kcal = 4.184e+9 µJ
By using this conversion factor, you can easily convert any energy from kilocalories to microjoule with precision.
How to Convert kcal to µJ?
Converting from kcal to µJ is a straightforward process. Follow these steps to ensure accurate conversions from kilocalories to microjoule:
- Select the Kilocalories Value: Start by determining the kilocalories (kcal) value you want to convert into microjoule (µJ). This is your starting point.
- Multiply by the Conversion Factor: To convert kilocalories to microjoule, multiply the selected kcal value by 4.184e+9. This factor is essential for accurately converting from a larger unit (kcal) to a much smaller unit (µJ).
- Illustration of Multiplication:
- 1 kcal = 4.184e+9 µJ
- 10 kcal = 4.184e+10 µJ
- 100 kcal = 4.184e+11 µJ
- Find the Conversion Result: The result of this multiplication is your converted value in microjoule unit. This represents the same energy but in a different unit.
- Save Your Microjoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in microjoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the kilocalories value by 0.239005736138. This alternative method also gives you the correct energy in microjoules.
- Illustration of Division:
- µJ = kcal ÷ 0.239005736138

Kilocalories to Microjoule Examples
Example 1:
Convert 0.9 Kilocalories to Microjoule.
Solution:
We know that one Kilocalories is equivalent to 4.184e+9 Microjoule.
Therefore,
0.9 kcal = 0.9 x 4.184e+9 µJ.
0.9 kcal = 3.7656e+9 µJ.
Hence, 0.9 Kilocalories is approximately equal to 3.7656e+9 Microjoule.
Example 2:
Convert 2 Kilocalories to Microjoule.
Solution:
We know that one Kilocalories is equivalent to 4.184e+9 Microjoule.
