Convert kilowatt-second to joule
Please provide values below to convert kilowatt-second [kW*s] to joule [J], or Convert joule to kilowatt-second.
1 kW*s = 1000 J. To convert kilowatt-second to joule, multiply the value by 1000; to go the other way, divide by it (1 J = 0.001 kW*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 kW*s = 1000 J
- 1 J = 0.001 kW*s
- 10 kW*s = 10000 J
- 100 kW*s = 100000 J
How to Convert Kilowatt-Second to Joule
1 kW*s = 1000 J
Example: convert 15 kW*s to J:
15 kW*s = 15 × 1000 J = 15000 J

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.
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 kilowatt-second in joule?
1 kilowatt-second (kW*s) = 1000 joule (J).
How do you convert kilowatt-second to joule?
Multiply the kilowatt-second value by 1000. For example, 25 kW*s × 1000 = 25000 J.
What is 10 kilowatt-second in joule?
10 kW*s = 10000 J.
Which unit is larger, the kilowatt-second or the joule?
The kilowatt-second is the larger unit: 1 kW*s = 1000 J.
