The formula
kWh = Wh × 0.001
Worked through with a real value: 10 watt hours = 0.01 kilowatt hours.
Going the other way: Wh = kWh × 1000, so 1 kilowatt hour = 1000 watt hours.
What each unit is
- watt hour Wh
- The energy consumed by one watt of power in one hour, equal to 3,600 joules. Household electricity meters measure consumption in kilowatt-hours.
- kilowatt hour kWh
- A thousand watt-hours, or 3.6 megajoules. The standard unit for household and industrial electricity consumption.
Where these come from
- 1 watt hour = 3600 joules
- 1 kilowatt hour = 3600000 joules
Every other number on this page is computed from those, and each category is pinned to conversions worked out by hand from the units' primary definitions before it ships.
