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

Joule/second: Definition and Use
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.
Kilojoule/second: Definition and Use
A kilojoule per second (kJ/s) is a unit of power equivalent to one kilojoule of energy transferred or converted per second.
History/Origin
The kilojoule per second is derived from the SI units of energy (joule) and time (second), and has been used in scientific and engineering contexts to measure power, especially in fields like physics and energy studies.
Current Use
It is used to quantify power in various applications, including electrical power, mechanical power, and energy transfer rates, particularly where kilojoules and seconds are the relevant units.
Joule/second to Kilojoule/second: Frequently Asked Questions
What is 1 joule/second in kilojoule/second?
1 joule/second (J/s) = 0.001 kilojoule/second (kJ/s).
How do you convert joule/second to kilojoule/second?
Multiply the joule/second value by 0.001. For example, 25 J/s × 0.001 = 0.025 kJ/s.
What is 10 joule/second in kilojoule/second?
10 J/s = 0.01 kJ/s.
Which unit is larger, the joule/second or the kilojoule/second?
The kilojoule/second is the larger unit: 1 J/s equals only 0.001 kJ/s.
