Divide the quantity of kilojoules by 3,600 to convert it to kilowatt-hours. The outcome will produce the same quantity of energy in kilowatt-hours.
Determine the conversion factor
Kilowatt-hours and kilojoules are both measures of energy. The equivalent of one kilowatt-hour is 3,600,000 joules. One kilojoule is equal to 1000 joules, hence one kilowatt-hour contains 3,600 kilojoules. The kilojoule to kilowatt-hour conversion factor is 3,600.
Subtract the conversion value.
Divide the quantity of kilojoules by 3,600 to convert it to kilowatt hours. For example: 7200 kilojoules / 3,600 = 2.
Identify the solution
The final step is to identify the answer with the appropriate energy unit. 7200 kilojoules = 2 kilowatt-hours, to continue with the example.
