Unit Information
Joule (J)
The joule is the SI unit of energy. It is equal to the energy transferred when applying a force of one newton through a distance of one meter.
1 J = 0.000278 Wh1 J = 0.001 kJ1 J = 0.000239 kcal
Watt-hour (Wh)
The watt-hour is a unit of energy equal to 3600 joules. It represents the energy equivalent to a power of one watt sustained for one hour.
1 Wh = 3600 J1 Wh = 3.6 kJ1 Wh = 0.001 kWh
