About kilowatt hours and joules
Kilowatt Hour (kWh)
A kilowatt-hour (kWh) is 1,000 watt-hours, or 3.6 million joules. It is the "unit" charged on household electricity bills.
Joule (J)
The joule (J) is the SI unit of energy: the work done by a force of one newton over one meter. One watt is one joule per second.
