kWh to Wh Converter - Kilowatt-hour to Watt-hour
Kilowatt-hour (kWh) to Watt-hour (Wh)
Direct answer
1 kWh = 1,000 Wh
Wh = kWh × 1,000
Converter
Conversion formula
Wh = kWh × 1,000
kWh = Wh × 0.001
Example: 10 kWh = 10 × 1,000 = 10,000 Wh.

Kilowatt-hour to Watt-hour Conversion
This page explains converting between kilowatt-hours (kWh) and watt-hours (Wh). Both are units of energy derived from the joule, with kilowatt-hour being a larger unit.
Definition
A kilowatt-hour (kWh) is a unit of energy equal to one kilowatt of power expended for one hour. A watt-hour (Wh) is a unit of energy equal to one watt of power expended for one hour.
Principle
The conversion factor of 1,000 is based on the metric prefix 'kilo,' which means thousand. Therefore, 1 kilowatt-hour contains 1,000 watt-hours.
Assumptions
- The conversion uses the standard metric definition where 'kilo' equals 1,000.
- Both units are defined in relation to the same time unit (hour) and base power unit (watt).
Cautions
- The provided example calculation (10 kWh = 10,000 Wh) is for illustration; actual results depend on your specific input.
- When performing conversions, check that the required precision for your calculation is maintained.
