Convert kilojoule to kilowatt-second
Please provide values below to convert kilojoule [kJ] to kilowatt-second [kW*s], or Convert kilowatt-second to kilojoule.
1 kJ = 1 kW*s. To convert kilojoule to kilowatt-second, multiply the value by 1; to go the other way, divide by it (1 kW*s = 1 kJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kJ = 1 kW*s
- 1 kW*s = 1 kJ
- 10 kJ = 10 kW*s
- 100 kJ = 100 kW*s
How to Convert Kilojoule to Kilowatt-Second
1 kJ = 1 kW*s
Example: convert 15 kJ to kW*s:
15 kJ = 15 × 1 kW*s = 15 kW*s

Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
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.
Frequently Asked Questions
What is 1 kilojoule in kilowatt-second?
1 kilojoule (kJ) = 1 kilowatt-second (kW*s).
How do you convert kilojoule to kilowatt-second?
Multiply the kilojoule value by 1. For example, 25 kJ × 1 = 25 kW*s.
What is 10 kilojoule in kilowatt-second?
10 kJ = 10 kW*s.
Which unit is larger, the kilojoule or the kilowatt-second?
The kilowatt-second is the larger unit: 1 kJ equals only 1 kW*s.
