How to convert joules to kilowatt-hour?

To convert joules to kilowatt hours, follow these simple steps:

  1. Understand the Conversion Factor: 1 kilowatt hour (kWh) equals 3.6 million joules (J). This means that to convert joules to kilowatt hours, you need to divide the joules by this number.

  2. Use the Formula:
    [ \text{kWh} = \frac{\text{J}}{3,600,000} ]

  3. Perform the Calculation: For example, if you have 7,200,000 joules, calculate it like this:
    [ \text{kWh} = \frac{7,200,000}{3,600,000} = 2 \text{ kWh} ]

By following these steps, you can easily and accurately convert joules into kilowatt hours, spreading your energy knowledge further!
