Convert watt-hour to watt-second
Please provide values below to convert watt-hour [W*h] to watt-second [W*s], or Convert watt-second to watt-hour.
1 W*h = 3600 W*s. To convert watt-hour to watt-second, multiply the value by 3600; to go the other way, divide by it (1 W*s = 0.000277777777778 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 = 3600 W*s
- 1 W*s = 0.000277777777778 W*h
- 10 W*h = 36000 W*s
- 100 W*h = 360000 W*s
How to Convert Watt-Hour to Watt-Second
1 W*h = 3600 W*s
Example: convert 15 W*h to W*s:
15 W*h = 15 × 3600 W*s = 54000 W*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.
Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
Frequently Asked Questions
What is 1 watt-hour in watt-second?
1 watt-hour (W*h) = 3600 watt-second (W*s).
How do you convert watt-hour to watt-second?
Multiply the watt-hour value by 3600. For example, 25 W*h × 3600 = 90000 W*s.
