Convert watt-hour to kilowatt-hour
Please provide values below to convert watt-hour [W*h] to kilowatt-hour [kW*h], or Convert kilowatt-hour to watt-hour.
1 W*h = 0.001 kW*h. To convert watt-hour to kilowatt-hour, multiply the value by 0.001; to go the other way, divide by it (1 kW*h = 1000 W*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 W*h = 0.001 kW*h
- 1 kW*h = 1000 W*h
- 10 W*h = 0.01 kW*h
- 100 W*h = 0.1 kW*h
How to Convert Watt-Hour to Kilowatt-Hour
1 W*h = 0.001 kW*h
Example: convert 15 W*h to kW*h:
15 W*h = 15 × 0.001 kW*h = 0.015 kW*h

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.
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.
Frequently Asked Questions
What is 1 watt-hour in kilowatt-hour?
1 watt-hour (W*h) = 0.001 kilowatt-hour (kW*h).
How do you convert watt-hour to kilowatt-hour?
Multiply the watt-hour value by 0.001. For example, 25 W*h × 0.001 = 0.025 kW*h.
What is 10 watt-hour in kilowatt-hour?
10 W*h = 0.01 kW*h.
Which unit is larger, the watt-hour or the kilowatt-hour?
The kilowatt-hour is the larger unit: 1 W*h equals only 0.001 kW*h.
