Convert kilowatt-hour to watt-hour
Please provide values below to convert kilowatt-hour [kW*h] to watt-hour [W*h], or Convert watt-hour to kilowatt-hour.
1 kW*h = 1000 W*h. To convert kilowatt-hour to watt-hour, multiply the value by 1000; to go the other way, divide by it (1 W*h = 0.001 kW*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW*h = 1000 W*h
- 1 W*h = 0.001 kW*h
- 10 kW*h = 10000 W*h
- 100 kW*h = 100000 W*h
How to Convert Kilowatt-Hour to Watt-Hour
1 kW*h = 1000 W*h
Example: convert 15 kW*h to W*h:
15 kW*h = 15 × 1000 W*h = 15000 W*h

Kilowatt-Hour
A kilowatt-hour (kW·h) is a unit of energy equal to the energy transferred or used when a power of one kilowatt is sustained for one hour.
History/Origin
The kilowatt-hour originated in the late 19th century with the development of electrical power systems, becoming a standard unit for measuring electrical energy consumption and billing.
Current Use
It is widely used today in electricity billing, energy consumption monitoring, and in various engineering and scientific applications to quantify electrical energy usage.
Watt-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
