What is Kilojoule to Joule Conversion?
Kilojoule (kJ) and joule (J) are both units used to measure energy, but they serve different purposes depending on the scale of the measurement. If you ever need to convert kilojoule to joule, knowing the exact conversion formula is essential.
KJ to j Conversion Formula:
One Kilojoule is equal to 1000 Joule.
Formula: 1 kJ = 1000 J
By using this conversion factor, you can easily convert any energy from kilojoule to joule with precision.
How to Convert kJ to J?
Converting from kJ to J is a straightforward process. Follow these steps to ensure accurate conversions from kilojoule to joule:
- Select the Kilojoule Value: Start by determining the kilojoule (kJ) value you want to convert into joule (J). This is your starting point.
- Multiply by the Conversion Factor: To convert kilojoule to joule, multiply the selected kJ value by 1000. This factor is essential for accurately converting from a larger unit (kJ) to a much smaller unit (J).
- Illustration of Multiplication:
- 1 kJ = 1000 J
- 10 kJ = 10000 J
- 100 kJ = 100000 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 kilojoule value by 0.001. This alternative method also gives you the correct energy in joules.
- Illustration of Division:
- J = kj ÷ 0.001

Kilojoule to Joule Examples
Example 1:
Convert 0.7 Kilojoule to Joule.
Solution:
We know that one Kilojoule is equivalent to 1000 Joule.
Therefore,
0.7 kJ = 0.7 x 1000 J.
0.7 kJ = 700 J.
Hence, 0.7 Kilojoule is approximately equal to 700 Joule.
Example 2:
Convert 8 Kilojoule to Joule.
Solution:
We know that one Kilojoule is equivalent to 1000 Joule.
Therefore,
8 kJ = 8 x 1000 J.
8 kJ = 8000 J.
Hence, 8 Kilojoule is approximately equal to 8000 Joule.
Example 3:
Convert 11 Kilojoule to Joule.
Solution:
We know that one Kilojoule is equivalent to 1000 Joule.
Therefore,
11 kJ = 11 x 1000 J.
11 kJ = 11000 J.
Hence, 11 Kilojoule is approximately equal to 11000 Joule.
Example 4:
Convert 317 Kilojoule to Joule.
Solution:
We know that one Kilojoule is equivalent to 1000 Joule.
