To convert watt-hours to kilojoules, enter the value in the first field. The result in kilojoules is calculated automatically using the exact conversion factor.

1 Wh = 3.6 kJ
1 kJ ≈ 0.277777777778 Wh

Formula: kJ = Wh × 3.6
Wh = kJ × 5/18

Definitions: 1 Wh = 3600 J; 1 kJ = 1000 J

The watt-hour (Wh) is the energy of one watt working for one hour, exactly 3,600 joules. It is used for the capacity of phone, laptop and power bank batteries and for small amounts of electricity.

The kilojoule (kJ) is 1,000 joules. It is used for food energy on nutrition labels in Australia, New Zealand and Europe, often next to kcal, and for reaction energies in chemistry.

See the conversion table with commonly used values, handy for quick reference or study.
