Convert watt-second to joule
Please provide values below to convert watt-second [W*s] to joule [J], or Convert joule to watt-second.
1 W*s = 1 J. To convert watt-second to joule, multiply the value by 1; to go the other way, divide by it (1 J = 1 W*s). 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*s = 1 J
- 1 J = 1 W*s
- 10 W*s = 10 J
- 100 W*s = 100 J
How to Convert Watt-Second to Joule
1 W*s = 1 J
Example: convert 15 W*s to J:
15 W*s = 15 × 1 J = 15 J

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.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
Frequently Asked Questions
What is 1 watt-second in joule?
1 watt-second (W*s) = 1 joule (J).
How do you convert watt-second to joule?
Multiply the watt-second value by 1. For example, 25 W*s × 1 = 25 J.
What is 10 watt-second in joule?
10 W*s = 10 J.
Which unit is larger, the watt-second or the joule?
The joule is the larger unit: 1 W*s equals only 1 J.
