Kilojoule (kJ) and watt-second (Watt-second) 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 watt-second, knowing the exact conversion formula is essential.
KJ to watt-second Conversion Formula:
One Kilojoule is equal to 1000 Watt-second.
Formula: 1 kJ = 1000 Watt-second
By using this conversion factor, you can easily convert any energy from kilojoule to watt-second with precision.
How to Convert kJ to Watt-second?
Converting from kJ to Watt-second is a straightforward process. Follow these steps to ensure accurate conversions from kilojoule to watt-second:
- Select the Kilojoule Value: Start by determining the kilojoule (kJ) value you want to convert into watt-second (Watt-second). This is your starting point.
- Multiply by the Conversion Factor: To convert kilojoule to watt-second, multiply the selected kJ value by 1000. This factor is essential for accurately converting from a larger unit (kJ) to a much smaller unit (Watt-second).
- Illustration of Multiplication:
- 1 kJ = 1000 Watt-second
- 10 kJ = 10000 Watt-second
- 100 kJ = 100000 Watt-second
- Find the Conversion Result: The result of this multiplication is your converted value in watt-second unit. This represents the same energy but in a different unit.
- Save Your Watt-second Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in watt-seconds.
- 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 watt-seconds.
- Illustration of Division:
- Watt-second = kj ÷ 0.001

Kilojoule to Watt-second Examples
Example 1:
Convert 0.8 Kilojoule to Watt-second.
Solution:
We know that one Kilojoule is equivalent to 1000 Watt-second.
Therefore,
0.8 kJ = 0.8 x 1000 Watt-second.
0.8 kJ = 800 Watt-second.
Hence, 0.8 Kilojoule is approximately equal to 800 Watt-second.
Example 2:
Convert 7 Kilojoule to Watt-second.
Solution:
We know that one Kilojoule is equivalent to 1000 Watt-second.
