Convert kilowatt-second to kilojoule

Enter a value below to convert kilowatt-second [kW*s] to kilojoule [kJ]. Reverse conversion: Convert kilojoule to kilowatt-second.

1 kW*s = 1 kJ. To convert kilowatt-second to kilojoule, multiply the value by 1; to go the other way, divide by it (1 kJ = 1 kW*s). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Kilowatt-Second to Kilojoule: Quick Reference

  • 1 kW*s = 1 kJ
  • 1 kJ = 1 kW*s
  • 10 kW*s = 10 kJ
  • 100 kW*s = 100 kJ



How to Convert Kilowatt-Second to Kilojoule

1 kW*s = 1 kJ

Example: convert 15 kW*s to kJ:
15 kW*s = 15 × 1 kJ = 15 kJ

Kilowatt-Second: Definition and Use

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.


Kilojoule: Definition and Use

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 to Kilojoule: Frequently Asked Questions

What is 1 kilowatt-second in kilojoule?

1 kilowatt-second (kW*s) = 1 kilojoule (kJ).

How do you convert kilowatt-second to kilojoule?

Multiply the kilowatt-second value by 1. For example, 25 kW*s × 1 = 25 kJ.

What is 10 kilowatt-second in kilojoule?

10 kW*s = 10 kJ.

Which unit is larger, the kilowatt-second or the kilojoule?

The kilojoule is the larger unit: 1 kW*s equals only 1 kJ.
