Show the working

1 kJ = 0.000277777777778 kWh
1 × 0.000277777777778 = 0.000277777777778 kWh

How to convert kilojoules to kilowatt-hours

1 kWh = 3,600 kJ, so divide by 3,600 to go from kilojoules to kilowatt-hours (1 kJ = 0.000277777777778 kWh).

kWh = kJ ÷ 3,600
kJ = kWh × 3,600

Worked example:

1 kJ = 0.000277777777778 kWh
5 × 0.000277777777778 = 0.00138888888889 kWh
