One Kilocalories is equal to 4184 Rontojoule.
Formula: 1 kcal = 4184 rJ
By using this conversion factor, you can easily convert any energy from kilocalories to rontojoule with precision.
How to Convert kcal to rJ?
Converting from kcal to rJ is a straightforward process. Follow these steps to ensure accurate conversions from kilocalories to rontojoule:
- Select the Kilocalories Value: Start by determining the kilocalories (kcal) value you want to convert into rontojoule (rJ). This is your starting point.
- Multiply by the Conversion Factor: To convert kilocalories to rontojoule, multiply the selected kcal value by 4184. This factor is essential for accurately converting from a larger unit (kcal) to a much smaller unit (rJ).
- Illustration of Multiplication:
- 1 kcal = 4184 rJ
- 10 kcal = 4.184e+31 rJ
- 100 kcal = 4.184e+32 rJ
- Find the Conversion Result: The result of this multiplication is your converted value in rontojoule unit. This represents the same energy but in a different unit.
- Save Your Rontojoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in rontojoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the kilocalories value by 2.390057e-31. This alternative method also gives you the correct energy in rontojoules.
- Illustration of Division:
- rJ = kcal ÷ 2.390057e-31

Kilocalories to Rontojoule Examples
Example 1:
Convert 0.4 Kilocalories to Rontojoule.
Solution:
We know that one Kilocalories is equivalent to 4184 Rontojoule.
Therefore,
0.4 kcal = 0.4 x 4184 rJ.
0.4 kcal = 1673.6 rJ.
Hence, 0.4 Kilocalories is approximately equal to 1673.6 Rontojoule.
Example 2:
Convert 3 Kilocalories to Rontojoule.
Solution:
We know that one Kilocalories is equivalent to 4184 Rontojoule.
Therefore,
3 kcal = 3 x 4184 rJ.
3 kcal = 1.2552e+31 rJ.
Hence, 3 Kilocalories is approximately equal to 1.2552e+31 Rontojoule.
Example 3:
