Convert kilowatt to joule/second
Please provide values below to convert kilowatt [kW] to joule/second [J/s], or Convert joule/second to kilowatt.
1 kW = 1000 J/s. To convert kilowatt to joule/second, multiply the value by 1000; to go the other way, divide by it (1 J/s = 0.001 kW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW = 1000 J/s
- 1 J/s = 0.001 kW
- 10 kW = 10000 J/s
- 100 kW = 100000 J/s
How to Convert Kilowatt to Joule/second
1 kW = 1000 J/s
Example: convert 15 kW to J/s:
15 kW = 15 × 1000 J/s = 15000 J/s

Kilowatt
A kilowatt (kW) is a unit of power equal to 1,000 watts, used to measure the rate of energy transfer or consumption.
History/Origin
The kilowatt was introduced as part of the metric system to provide a practical unit for measuring larger power outputs, especially in engineering and electrical contexts, and has been widely adopted since the 20th century.
Current Use
The kilowatt is commonly used today to specify the power output of engines, electrical appliances, and power generation facilities, as well as in billing for electricity consumption and capacity ratings.
Joule/second
The joule per second (J/s) is a unit of power representing the rate at which energy is transferred or converted, equivalent to one watt.
History/Origin
The joule per second has been used as a measure of power since the adoption of the SI system, where the watt (W) became the standard unit of power, with 1 J/s = 1 W.
Current Use
J/s is primarily used in scientific and engineering contexts to quantify power, especially in physics and electrical engineering, often interchangeably with watts.
Frequently Asked Questions
What is 1 kilowatt in joule/second?
1 kilowatt (kW) = 1000 joule/second (J/s).
How do you convert kilowatt to joule/second?
Multiply the kilowatt value by 1000. For example, 25 kW × 1000 = 25000 J/s.
What is 10 kilowatt in joule/second?
10 kW = 10000 J/s.
Which unit is larger, the kilowatt or the joule/second?
The kilowatt is the larger unit: 1 kW = 1000 J/s.
