By using this conversion factor, you can easily convert any energy from kilowatt-hour to joule with precision.
How to Convert kWh to J?
Converting from kWh to J is a straightforward process. Follow these steps to ensure accurate conversions from kilowatt-hour to joule:
- Select the Kilowatt-hour Value: Start by determining the kilowatt-hour (kWh) value you want to convert into joule (J). This is your starting point.
- Multiply by the Conversion Factor: To convert kilowatt-hour to joule, multiply the selected kWh value by 3600000. This factor is essential for accurately converting from a larger unit (kWh) to a much smaller unit (J).
- Illustration of Multiplication:
- 1 kWh = 3600000 J
- 10 kWh = 36000000 J
- 100 kWh = 360000000 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 kilowatt-hour value by 0.0000003. This alternative method also gives you the correct energy in joules.
- Illustration of Division:
- J = kwh ÷ 0.0000003

Kilowatt-hour to Joule Examples
Example 1:
Convert 0.5 Kilowatt-hour to Joule.
Solution:
We know that one Kilowatt-hour is equivalent to 3600000 Joule.
Therefore,
0.5 kWh = 0.5 x 3600000 J.
0.5 kWh = 1800000 J.
Hence, 0.5 Kilowatt-hour is approximately equal to 1800000 Joule.
Example 2:
Convert 8 Kilowatt-hour to Joule.
Solution:
We know that one Kilowatt-hour is equivalent to 3600000 Joule.
Therefore,
8 kWh = 8 x 3600000 J.
8 kWh = 28800000 J.
Hence, 8 Kilowatt-hour is approximately equal to 28800000 Joule.
Example 3:
Convert 62 Kilowatt-hour to Joule.
Solution:
We know that one Kilowatt-hour is equivalent to 3600000 Joule.
Therefore,
62 kWh = 62 x 3600000 J.
62 kWh = 223200000 J.
Hence, 62 Kilowatt-hour is approximately equal to 223200000 Joule.
Example 4:
Convert 419 Kilowatt-hour to Joule.
Solution:
We know that one Kilowatt-hour is equivalent to 3600000 Joule.
