Convert watt-hour to kilowatt-second
Please provide values below to convert watt-hour [W*h] to kilowatt-second [kW*s], or Convert kilowatt-second to watt-hour.
1 W*h = 3.6 kW*s. To convert watt-hour to kilowatt-second, multiply the value by 3.6; to go the other way, divide by it (1 kW*s = 0.277777777778 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 = 3.6 kW*s
- 1 kW*s = 0.277777777778 W*h
- 10 W*h = 36 kW*s
- 100 W*h = 360 kW*s
How to Convert Watt-Hour to Kilowatt-Second
1 W*h = 3.6 kW*s
Example: convert 15 W*h to kW*s:
15 W*h = 15 × 3.6 kW*s = 54 kW*s

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-Second
A kilowatt-second (kW·s) is a unit of energy equal to the energy transferred or converted when a power of one kilowatt is applied for one second.
History/Origin
The kilowatt-second has been used historically in physics and engineering to quantify energy, especially in contexts where power and time are relevant, but it is less common than other energy units like joules or kilowatt-hours.
Current Use
Today, the kilowatt-second is primarily used in specialized fields such as electrical engineering and energy calculations, often for convenience in measuring short-term energy transfer, but it is largely replaced by the joule in most applications.
Frequently Asked Questions
What is 1 watt-hour in kilowatt-second?
1 watt-hour (W*h) = 3.6 kilowatt-second (kW*s).
How do you convert watt-hour to kilowatt-second?
Multiply the watt-hour value by 3.6. For example, 25 W*h × 3.6 = 90 kW*s.
What is 10 watt-hour in kilowatt-second?
10 W*h = 36 kW*s.
Which unit is larger, the watt-hour or the kilowatt-second?
The watt-hour is the larger unit: 1 W*h = 3.6 kW*s.
