Convert joule/second to kilowatt
Please provide values below to convert joule/second [J/s] to kilowatt [kW], or Convert kilowatt to joule/second.
1 J/s = 0.001 kW. To convert joule/second to kilowatt, multiply the value by 0.001; to go the other way, divide by it (1 kW = 1000 J/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 J/s = 0.001 kW
- 1 kW = 1000 J/s
- 10 J/s = 0.01 kW
- 100 J/s = 0.1 kW
How to Convert Joule/second to Kilowatt
1 J/s = 0.001 kW
Example: convert 15 J/s to kW:
15 J/s = 15 × 0.001 kW = 0.015 kW

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.
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.
Frequently Asked Questions
What is 1 joule/second in kilowatt?
1 joule/second (J/s) = 0.001 kilowatt (kW).
How do you convert joule/second to kilowatt?
Multiply the joule/second value by 0.001. For example, 25 J/s × 0.001 = 0.025 kW.
What is 10 joule/second in kilowatt?
10 J/s = 0.01 kW.
Which unit is larger, the joule/second or the kilowatt?
The kilowatt is the larger unit: 1 J/s equals only 0.001 kW.
